85.0 grams of NaN3 decompose at 75 degrees Cesius and at 2.3atm. Of pressure. What volume of N2 will be made according to the equation: 2NaN3(g) > 2Na(g) + 3N2(g)

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.
