Using atomic masses C=12 H=1 O=16
Molar mass of ethanol C2H5OH = 24+5+16+1 =46
Use the percent expression
Percentage of X = (amount of X/ total amount [molar mass here]) X 100
%C = 24/46 X100
%H = 6/46 x100
%O =16/46 x100
Use calculator to work out.. check no calculation errors ... should all add up to 100%
