For many purposes we can treat methane (CH) as an ideal gas at temperatures above its boiling point of -161. °C. Suppose the temperature of a sample of methane gas is raised from -24.0 °C to 18.0 °C, and at the same time the pressure is changed. If the initial pressure was 6.2 atm and the volume increased by 35.0%, what is the final pressure? Round your answer to 2 significant digits. | atm
