You mean molecular mass or moler mass, not Atomic Mass!
Add up the atomic masses of all the atoms in the molecule.
mass of h = 8 atoms of h/molecule * 1.00794 g/mol = 8.06352g/mol of h in c7h8 mass of c7h8 = 8 atoms of H/molecule * 1.00794 g/mol + 7 atoms/molecule of C * 12.0107 g/mol = 92.13842 g/mol h / c7h8 = 8.06352 / 92.13842 = 0.08752 0.08752 = 8.752% = 9%
Atomic mass = Mass of protons + Mass of neutrons
Atomic mass = mass of protons + mass of neutrons.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.

you can find electrons by subtract the atomic number and atomic mass.
