WebOct 14, 2013 · Reaction equation: HX +NaOH ----> H2O + NaX 0.0688L x 0.750 M = 0.0516 moles OH -. That is also the moles of H +. Because HX is in a 1:1 ratio, the moles of H + is the same as the moles of HX. For example, if you have one mole of NaCl, you then have one mole of sodium ions and one mole of Chloride ions. WebFinding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.
