If one C has a mass of 12amu, then 2 of them should weigh how much? Four groups of 2 C atoms will weigh how much also? That mass will be the same as 3 of atom Z, so divide the mass of 8 C atoms by three.

1 C atom weighs 12 amu. 8 of them should weigh 8 times 12amu\[8 C atoms * (\frac{12amu}{1C atom})\]
