Mixtures of He and O are used in scuba diving tanks to help prevent "the bends."?

For an immersion in particular, 46 L He at 25 * C and 1.0 atm and 12 l O2 at 25 * C and 1.0 atm is pumped into a tank with a volume of 5.0 l. Calculate the partial pressure of each gas and total pressure in the deposit at 25 ° C. (Temp = 298 K and gas constant = .0821 L * atm / mol * K) in the *** How can I solve this?

PV = nRT (Pressure) (volume) = (number of moles) (gas constant 0.0821) (temperature in degrees Kelvin) I think it will work … just plug in numbers. The Sorry if this does not work ….
