A deep sea diver uses a gas cylinder of 10.0 L and a content of 51.4 g of O2 and 32.5 g of He.
Calculate the partial pressure of each gas and the total pressure of the temperature of the gas is 16 C.

Damon,
P V = n R T
T = 16 + 273
V = 10 L = .01 m^3
n of O2 = 51.4/32
n of He = 32.5/4
calculate P of each
then add to get total
