A deep-sea diver uses a gas cylinder with a volume of 10.0 L and a content of 51.2 g O2 and 32.6 g He. Calculate the partial pressure of each gas and the total pressure if the temperature of the gas is 19oC.
since we're given the total temperature and volume, we can calculate the partial pressures of each gas individually using the ideal gas law.....
calculate mol O2 and mol He:
now, partial pressures.....
the total pressure is the sum of the partial pressures......
