Trimix is a general name for a type of gas blend used by technical divers and contains nitrogen, oxygen and helium. In one Trimix blend, the partial pressures of each gas are 55.0 atm oxygen, 90.0 atm nitrogen, and 51.0 atm helium. What is the percent oxygen (by volume) in this trimex blend?

A 4.72 mol sample of freon gas was placed in a balloon. Adding 3.50 mol of freon gas to the balloon increased its volume to 22.5 L. What was the initial volume of the balloon?
