Reacting 959 mol of SiO2 with excess carbon yields 28.8 kg of SiC. What is the percentage yield?

SiO2 + 3C--> SiC + 2 CO

  • chemistry -

    You must determine first the theoretical yield.
    Using the coefficients in the balanced equation, convert moles SiO2 to moles SiC.

    Convert moles SiC to grams. g = moles x molar mass. This is the theoretical yield.

    %yield = [actual yield/theoretical yield]*100 = ??
    actual yield is given in the problem as 28.8 kg but you must change this to grams OR change the theoretical yield to kg.
