Therefore, a100-g sample of water contains 11.2 g of hydrogenatoms and 88.8 g of oxygen atoms.A hydrocarbon is a compound that contains mostly carbon and hydrogen. Calculate the percentcomposition (by mass) of the following hydrocarbon: CH22Enter the percentages of carbon and hydrogen numerically to four significant figures, separated bycommas.The periodic table will be useful when doing thisproblem.
