SCUBA divers use Dalton's law all the time. The air in their tank is a mixture of gases. The pressure around the tank changes as the diver descends and ascends, and the pressure in the tank changes as the diver breathes taking the gas out of the tank. If a diver has a tank with the following gas mixture and pressures at the end of their dive, what is the total pressure in their tank?
O2 = 3.03 psi
N2 = 11.32 psi
Ar = 0.14 psi
H2O - 0.18 psi
CO2 = 0.0070 psi
