Problem

A deep-sea diver uses a gas cylinder with a volume of 10.0 L and a content of 51.3 g of O2 and 32.7 g of He.

Calculate the partial pressure of each gas and the total pressure if the temperature of the gas is 19 oC.

Solution

First, calculate the number of moles of O2 and He present in the tank:

Molar mass O2 = 16 g/mol x 2 = 32 g/mol
Molar mass He = 4.0 g/mol
