You are reacting hydrogen gas with tin oxide to purify tin. SnO2 + 2 H2 → Sn + 2 H2O. You have 45.8L of H2 gas and 351.3g of SnO2. What will be the limiting reactant, and how much of the excess reactant will be left over?

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
