multiply the mass by the percent to find the element masses
divide the element masses by the amu's to find the number of atoms
adjust for fractions by dividing through by the fraction
The percent composition by mass of an unknown compound with a molecular mass of 60.052 amu is 40.002% C, 6.7135% H, and 53.284% O. Determine the compound's empirical and molecular formulas.
