A gas that exerts a pressure of 6.20 atm in a container with a volume of [tex]\( V \, \text{mL} \)[/tex] will exert a pressure of 9.150 atm when transferred to a container with a volume of 322 mL.

Assume that the number of moles and the temperature remain constant.

Find the volume [tex]\( V \)[/tex].

[tex]\( V = \, \text{mL} \)[/tex]

(Note: Ensure to use the ideal gas law or relevant principles to find the volume.)



Answer :

To solve this problem, we can use Boyle’s Law, which states that the pressure of a gas times its volume is constant when the temperature and the number of moles of gas remain unchanged. Mathematically, Boyle's Law is expressed as [tex]\(P_1 \times V_1 = P_2 \times V_2\)[/tex], where:
- [tex]\(P_1\)[/tex] is the initial pressure,
- [tex]\(V_1\)[/tex] is the initial volume,
- [tex]\(P_2\)[/tex] is the final pressure,
- [tex]\(V_2\)[/tex] is the final volume.

Given:
- [tex]\(P_1 = 6.20 \,\text{atm}\)[/tex]
- [tex]\(P_2 = 9.150 \,\text{atm}\)[/tex]
- [tex]\(V_2 = 322 \,\text{mL}\)[/tex]
- [tex]\(V_1 = ? \,\text{mL}\)[/tex]

We need to find the initial volume [tex]\(V_1\)[/tex].

1. Write down Boyle’s Law equation:
[tex]\[ P_1 \times V_1 = P_2 \times V_2 \][/tex]

2. Substitute the given values into the equation:
[tex]\[ 6.20 \times V_1 = 9.150 \times 322 \][/tex]

3. Calculate the right side of the equation:
[tex]\[ 9.150 \times 322 = 2943.30 \][/tex]

4. Now the equation looks like this:
[tex]\[ 6.20 \times V_1 = 2943.30 \][/tex]

5. Solve for [tex]\(V_1\)[/tex] by dividing both sides of the equation by 6.20:
[tex]\[ V_1 = \frac{2943.30}{6.20} \][/tex]

6. Perform the division to find [tex]\(V_1\)[/tex]:
[tex]\[ V_1 \approx 475.21 \,\text{mL} \][/tex]

Therefore, the initial volume [tex]\(V_1\)[/tex] of the gas is approximately [tex]\(475.21 \,\text{mL}\)[/tex].
