Pressure Problem

Question

A Sample of Carbon Dioxide gas at a pressure of 0.933 atm and a temperature of 24.6°C, occupies a volume of 12.8 liters. If the gas is allowed to expand at a constant temperature to a volume of 22.2 liter, the pressure of the gas sample will be ? atm.

Answer 1

At constant temperature, we are dealing with Boyle's Law: P1/V1 = P2/V2

P1 = 0.933 atm

V1 = 12.8 L

P2 = ?

V2 = 22.2 L

0.933 atm/12.8 L = P2/22.2 L

P2 = 1.62 atm
