H2so4 + 2naoh --> h2o + na2so4

how many molecules of water are produced if 2.0g of sodium sulfate are produced in the above reaction?

plz i really need : (

2.0 g NaSO4(1 mol NaSO4/142.04 g)(1 mol H2O/1 mol NaSO4)(18.02 g/1 mol H2O)(6.02x10^23 g/ 1 molecule H2O)= 1.5275 molecules of water

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.
