EXAMPLE 6-11 Applying the Ideal Gas Equation to a Mixture of Gases What is the pressure, in bar, exerted by a mixture of 1.0 g H2 and 5.00 g He when the mixture is confined to a volume of 5.0 L at 20 °C? Analyze For fixed T and V, the total pressure of a mixture of gases is determined by the total number of moles of gas: Ptot = ntotRT/V. Solve ntot = (1.0g Hz x 1 mol Hy)...
