Which has more S by mass: 1 gram of MgS or 1 gram of Na2S? Compared to the mass of sulfur in a 1.00 g sample of MgS, the mass of sulfur in a 1.00 g sample of Na2S is You Might Also Like Determine the number of protons, neutrons, and electrons in the following: 25 X 12 What is the chemical symbol for an atom that has 29 protons and 36 neutrons? Calculate the molar heat of fusion of this substance in kJ/mol. 300g of this unknown substance, with a molar mass of 180 g/mol, gives off 65 kJ of energy as it freezes. A chemist prepares a solution of magnesium bromide MgBr2 by measuring A 14.01 g sample of N2 reacts with 3.02 g of H2 to form ammonia (NH3).
