H2SO4 → H2O + SO3 If I start with 89 grams of sulfuric acid and produce 7.1 grams of water, what is my percent yield?​

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.
