Is hydrogen lighter than aspirin?
Yes, definitely. The formula for aspirin, or acetylsalicyclic acid, is C9H8O4, having a molecular mass of 180.157 g/mole. Hydrogen's formula is H2, having a molecular mass of 2.02 g/mole. So if you had a liter of hydrogen and an equal amount of molecules of aspirin, the hydrogen would be about 1/5 of a kilogram lighter.

A 134.50 g sample of aspirin is made up of 6.03 g of hydrogen 80.70 g of carbon and 47.77 g of oxygen What is the percent by mass of each element in aspirin?
4.5 % hydrogen 60% carbon 35.5% oxygen to find say, the percentage of hydrogen, take the amount of hydrogen(6.03) and divide it by the total amount(134.50) with this new answer (.044832714) move the decimal over twice, and round to the highest tenths place. i hope this helps you.
