A gaseous mixture consists of 6.95 g of N2, 4.75 g of O2, and 2.75 g of He. What volume does this mixture occupy at 23°C and 1.35 atm pressure?

    Convert grams of the gases to mols. mol = grams/molar mass.
    Add mols to find total mols = n, then use PV = nRT to solve for volume at the conditions listed. Don't forget T must be in kelvin.
