Trimix gas is used for very deep diving. It is composed of three gases, usually helium, nitrogen and oxygen. The composition is denoted as percentage of oxygen / percentage of helium, e.g. 17/50 is Trimix with 17% oxygen, 50% helium and the balance is nitrogen. Assume these as mass percents. Calculate: a. the mass percentage of nitrogen in the mixture b. the mole fraction of each gas in the mixture.
