Consider the following unbalanced chemical equation. H2S(g) + O2(g) - SO2(g) + H2O(g)
Determine the maximum number of moles of SO2 produced from 6.00 moles of H2S and 5.00 moles of 02

You use the atomic number to find out how many protons and neutrons there are in the atom. you use the atomic mass to find out how many protons and electrons there are in the atom. 

The atomic nucleus made up from protons (yellow) and neutrons (blue) and held together by nuclear forces. nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. they bind protons and neutrons (“nucleons”) into atomic
