You need another number, to wit, the standard volume of a mole of gas at STP, which is 22.4 liters. The mass of one liter of oxygen is 32/22.4 grams. The given equation can be reduced to a simpler form which involves the molar volume.

seventy one.11% First diverse the molecular weight of each molecule by using how many each has (ex: MW of C is 12 and there are 2 molecules so 12x2=24). C2= 12x2=12 H2= 1x2=2 O4= 16x4=sixty 4 Then upload all of them as much as get the whole weight which equals ninety. 12+2+sixty 4=ninety Then divide the oxygen weight by using the whole weight and multiply by using one hundred to get the proportion. (sixty 4/ninety)x100=seventy one.11% wish this facilitates!
