The total mass of the products can be found by adding together the atomic masses of sodium (Na) and chlorine (Cl), and then multiplying by the stoichiometric coefficient of sodium chloride (NaCl) in the balanced chemical equation.
Atomic mass of Na = 22.99 amu
Atomic mass of Cl = 35.45 amu
(2Na x 22.99 amu) + (1Cl2 x 35.45 amu) = 45.98 amu + 70.90 amu = 116.88 amu
Therefore, the total mass of the products is 116.88 amu.
