how many grams of CO2 can be formed by the complete combustion of a 14.7 sample of C2H6 that is 92.4% pure?( assume the impurities contain no carbon)

  • chemistry -

    balance the equation:

    2C2H6+ 7O2 >> 4CO2 + 6H2O check that.

    moles C2H6= (14.7g*.924)/molmassC2H6

    massCO2= molesCO2*molmassCO2=2molesC2H6*molmassCO2

  • chemistry -

    plug in the molar mass? is mass the same as molar mass?
