A sample of a compound containing carbon and oxygen have a mass of 132 g. Experimental procedures showed that 36 g of this sample was carbon and the remaining 64g was oxygen. what is the percentage composition of the compound?
"\\%C=" "36g\\over 132g" "\\times 100\\%=27.27\\%"
"\\%O_2=" "64g\\over 132g" "\\times100\\%=48.48\\%"
"\\therefore" The compound is "27.27\\%Carbon" and "48.48\\%Oxygen" by mass
