what would the molarity of a solution be if you diluted 350 mL of 3 M NaOH to 1.4 Liters?

Answers

Answer 1

Answer:

0.75 M

Explanation:

Equation for dilution:

M1V1 = M2V2

Make units the same:

350 mL = 0.35 L

Plug the numbers into the equation

(3M) (0.35 L) = (M2) (1.4L)

Divide both sides by 1.4L

Which gives you 0.75 = M2

A presión de 3atm, 7L de un gas a temperatura constante experimenta un cambio ocupando un volumen de 0,5L ¿Cuál será la presión que ejerce? ayuda

Answers

Answer:

La presión que ejerce es 42 atm.

Explanation:

La ley de Boyle relaciona la presión y el volumen y dice que  el volumen ocupado por una determinada masa gaseosa a temperatura constante, es inversamente proporcional a la presión.

La ley de Boyle se expresa matemáticamente como:

P*V=k

Ahora es posible suponer que tienes un cierto volumen de gas V1 que se encuentra a una presión P1 al comienzo del experimento. Si varias el volumen de gas hasta un nuevo valor V2, entonces la presión cambiará a P2, y se cumplirá:

P1*V1= P2*V2

En este caso:

P1= 3 atmV1= 7 LP2= ?V2= 0.5 L

Reemplazando:

3 atm* 7 L= P2* 0.5 L

Resolviendo:

[tex]P2=\frac{3 atm*7 L}{0.5 L}[/tex]

P2= 42 atm

La presión que ejerce es 42 atm.

Answer:10.5

Explanation:

3atm x 7L / 0,5L = 10.5

What is the molarity of a solution of 58.7 grams of MgCl2 in 359 ml of solution?

Answers

Answer:

1.72 M

Explanation:

Molarity is the molar concentration of a solution. It can be calculated using the formula a follows:

Molarity = number of moles (n? ÷ volume (V)

According to the information provided in this question, the solution has 58.7 grams of MgCl2 in 359 ml of solution.

Using mole = mass/molar mass

Molar mass of MgCl2 = 24 + 35.5(2)

= 24 + 71

= 95g/mol

mole = 58.7g ÷ 95g/mol

mole = 0.618mol

Volume of solution = 359ml = 359/1000 = 0.359L

Molarity = 0.618mol ÷ 0.359L

Molarity = 1.72 M

Despite its appearance, air has a ‘thickness’ so when the sun is high in the sky the light travels through the air on a very much shorter path than when it is low on the horizon.

Imagine that air water and you are below the surface, the light from an overhead sun will be quite sharp and bright, but if lower in the sky it will have to travel through much more water to reach you, so will look less bright and sharp. It ma not seem the same, but the atmosphere is just like very thin water, and a low lying sun will be drastically reduced in strength, so all you will see is a sun with a shift to the red end of the spectrum as all the actinic part will be filtered away by that thicker atmosphere.

A chemist mixed two substances together: a blue powder with no smell and a colorless liquid with a strong smell. Their repeating groups of atoms are shown below on the left. After they were mixed, the chemist analyzed the results and found two substances. One ending substance had the repeating group of atoms shown below on the right. Is the ending substance the same substance as the blue powder? What happened to the atoms of the starting substances when the ending substances formed

Answers

Answer:

Vanished completely.

Explanation:

The atoms of starting substances are transformed into the ending substances because the starting substances mixed with each other and turn into new substances. The starting substances i.e. reactants vanished completely when the ending substances means products are formed completely so we can say that the vanishing of ending substance happened when the ending substances are formed.

The actual yield of a product in a reaction was measured as 4.20 g. If the theoretical yield of the product for the reaction is 4.88 g, what is the percentage yield of the product? (4 points) Question 17 options: 1) 82.6% 2) 84.2% 3) 86.1% 4) 88.0%

Answers

Answer:

3

Explanation:

remember the equation percentage yield = actual/ theoretical yield as

4.20/4.88 x 100

86.065 so 86.1.

hope this make sense:)

The percentage yield of the product is 86.1%. The correct option is 3) 86.1%

Calculating percentage yield

From the question, we are to calculate the percentage yield of the product

Percentage yield can be calculated from the formula,

[tex]Percentage \ yield = \frac{Actual\ yield}{Theoretical \ yield} \times 100\%[/tex]

From the given information,

Actual yield = 4.20 g

Theoretical yield = 4.88 g

Putting the parameters into the formula, we get

[tex]Percentage \ yield = \frac{4.20}{4.88} \times 100\%[/tex]

Percentage yield = 0.86065574 × 100%

Percentage yield = 86.065574%

Percentage yield ≅ 86.1%

Hence, the percentage yield of the product is 86.1%. The correct option is 3) 86.1%

The volume of the solution is given below which can be calculated using the molarity formula.

d. 2.18 litres

Molarity:

It is defined as the ratio of number of moles of solute to the volume of the solution.

It is given by:

M= n/V

What information do we have?

M= 0.420M

mass = 64.0 grams

Molar Mass= 74g/mol

To find:

Volume of solution=?

Calculation for number of moles:

n= m/ M

n= 64/70

n= 0.91 moles

Molarity=  n/V

0.420 M= 0.91 moles /V

V= 0.91/ 0.420

V= 2.1768 litres

Thus, the volume of the solution is 2.18 litres.

The equation below is for potassium oxide.
4K + O2 2K2O
What is the ratio of atoms of potassium to atoms of oxygen?

Answers

Answer:

The ratio of atoms of potassium to atoms of oxygen is  2:1

Explanation:

As the equation given is :

[tex]4K + O_2 -----> 2K_2O[/tex]

The product formed is 2 moles of potassium oxide .

Amount of potassium atom in the potassium oxide  is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .

But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .

Hence , we get 4 atoms of potassium and 2 atoms of oxygen .

Ratio of potassium to oxygen atoms is -   4:2

Therefore ,   2:1

Answers

Answer:

Explanation:

Robert Boyle was an Irish chemist and is famously referred to as the first modern chemist. He was born on the 25th of January, 1627 in Lismore, Ireland and died on the 31st, December 1691, London, United Kingdom.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

[tex] PV = K[/tex]

[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]

Where;

P1 is the original pressure.

P2 is the final pressure.

V1 is the original volume.

V2 is the final volume.

This ultimately implies that, ventilation which is typically governed by Boyle's Law, which states that at a constant temperature the pressure of a gas is directly proportional to its volume.

Explanation:

I just took the test! :)

The percentage by mass of solution formed by dissolving 36.0 grams of HCl in 98.0 grams of water is 36.7%.

How to calculate percentage by mass?

The percentage by mass of a solution can be calculated by dividing the mass of the solute by the mass of the solvent, then, multiplied by 100.

percent by mass = mass of solute/mass of solvent × 100

According to this question, 36.0 grams of HCl is dissolved in 98.0 grams of water. The percentage by mass is calculated as follows:

percent by mass = 36g/98g × 100

percent by mass = 36.7%.

Therefore, the percentage by mass of solution formed by dissolving 36.0 grams of HCl in 98.0 grams of water is 36.7%.
