Mixtures of helium and oxygen are used in scuba diving tanks to help prevent ‘the bends’, a
condition caused by nitrogen bubbles forming in the bloodstream. If 95 L of oxygen and 25
L of helium at STP are pumped into a scuba tank with a volume of 8.0 L, what is the partial
pressure of each gas in the tank and what is the total pressure in the tank at 25 oC?

mols O2 = 95/22.4 = ?
mols He = 25/22.4 = ?
Use PV = nRT and substitute mols O2 fo pO2.
Do same for He for pHe.

Ptotal = pHe + pO2.
