    More stoichiometry help

    Could someone please throw some example stoichiometry problems my way and help me check them? I'm still trying to finish a quiz from a week ago at school... I I could really use some where you have to convert moles to grams in the final step; I kept messing up on that in tutoring today.

    Example: How many grams of carbon dioxide are produced when 100g of propane (C_3H_8) undergoes complete combustion in air

    I can go through it if you like

    (I get an answer of 412.5g of CO_2
