Given:
[tex]P_{1} = \text{480 torr}[/tex]
[tex]V_{1} = \text{142 mL}[/tex]
[tex]V_{2} = \text{200 mL}[/tex]
Required:
[tex]P_{2}[/tex]
Strategy:
This is a gas law problem. What gas law should we use?
Since the given quantities are pressure and volume, we will use Boyle's law. According to this gas law, the pressure of a gas is inversely proportional to its volume keeping the amount of gas and its temperature constant.
The formula used for Boyle's law is
[tex]\boxed{P_{1}V_{1} = P_{2}V_{2}}[/tex]
where:
[tex]P_{1} = \text{initial pressure}[/tex]
[tex]V_{1} = \text{initial volume}[/tex]
[tex]P_{2} = \text{final pressure}[/tex]
[tex]V_{2} = \text{final volume}[/tex]
Solution:
Starting with the formula of Boyle's law
[tex]P_{1}V_{1} = P_{2}V_{2}[/tex]
Dividing both sides of the equation by V₂ to solve for P₂
[tex]P_{2} = P_{1} \times \dfrac{V_{1}}{V_{2}}[/tex]
Substituting the given values and solving for P₂
[tex]P_{2} = \text{480 torr} \times \dfrac{\text{142 mL}}{\text{200 mL}}[/tex]
Therefore, the final pressure is
[tex]\boxed{P_{2} = \text{340.8 torr}}[/tex]
Answer:
[tex]P_{2} = \text{340.8 torr}[/tex]
