Homework Help: Mixture Component Problem

  1. Feb 8, 2007 #1
    1. A mixture at T=300 K and P=100 kPa is made up of .1 oxygen, .2 carbon dioxide, and .7 Nitrogen. It is then heated to 300 kPa and 500 K. Find the mass of each component


    I originally thought using PV=NRT, ideal gas but there doesn't seem to be enough givens. Can you also find the molar mass of the mixture by doing:

    .7(28)+.2(44)+.1(32), so then you can find the mass of the component when you find the number of moles N but I am having problems doing that

    Yes, the question is incomplete. In addition, it's ambiguous, as it does not state whether .1, .2 and .7 are mass or molar (ie, volume) ratios (assuming they are ratios).
