WebNumber of moles of a substance = mass of the reactant ÷ molar mass of the reactant. Number of moles of Na = amount of Na in the reaction (in grams) ÷ molar mass of Na. Number of moles of Na = 4 grams ÷ 22.99 g/mole. Number of moles of Na = 0.17 moles of Na. Similarly: Number of moles of Cl 2 = 15 grams ÷ 70.90 g/mole WebSep 7, 2024 · What is the mass of a reactant? September 7, 2024 by Alexander Johnson. The law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. For example, the mass of sodium plus the mass of chlorine that reacts with the sodium equals the mass of the product sodium chloride.
