A 35 L tank of oxygen is at 315 K with an internal pressure of 190 atmospheres. Howmany moles of gas does the tank contain?

A balloon that can hold 85 L of air is inflated with 3.5 moles of gas at a pressure of 1.0 atmosphere. What is the temperature in C of the balloon?

CaCO3 decomposes at 1200 C to form CO2 gas and CaO. If 25 L of CO2 are collected at 1200C, what will the volume of this gas be after it cools to 25 C?
