What is the final pressure of a gas if a given sample at 300 ° C, 2.2 atm and 2.4 L is changed to 0 ° C and 1.0 L?

Question

Quizplus · Accepted Answer

We can use the combined gas law formula to solve this problem:
(P₁V₁/T₁) = (P₂V₂/T₂)
P₁ = 2.2 atm
V₁ = 2.4 L
T₁ = 300 °C + 273 = 573 K
P₂ = ?
V₂ = 1.0 L
T₂ = 0 °C + 273 = 273 K
(2.2 atm x 2.4 L)/(573 K) = (P₂ x 1.0 L)/(273 K)
Solving for P₂, we get:
P₂ = (2.2 atm x 2.4 L x 273 K)/(1.0 L x 573 K) = 2.5 atm
Therefore, the final pressure of the gas is 2.5 atm. The correct answer is choice C.
