Web29 aug. 2008 · 4 answers. 2.5 mol Mg3N2 x (6 mols H2O/1 mol Mg3N2) = mols H2O. Note that the numbers in the factor (that part inside the parentheses) actually are the coefficients in the balanced equation AND that the unit we don't want to keep (mols Mg3N2) cancel and the unit we want at the end (mols H2O) remain unaffected and is the unit for the answer. WebTo determine the molar mass multiply the molar mass of each element in the compound by the number of atoms of each element in the compound. (24.305gmol^-1 x 1) + (35.45gmol^-1 x 2) = 95.205 grams per mole. 30. A chemist dissolves a 3.83 g Ba (OH)2 in enough … WebApplications Antacid.
