The total mass of the products can be calculated by adding the atomic masses of sodium (Na) and chlorine (Cl), and multiplying by the stoichiometric coefficient (the number of moles) in the balanced chemical equation.
The atomic mass of sodium (Na) is approximately 22.99 amu, and the atomic mass of chlorine (Cl) is approximately 35.45 amu.
For the reaction 2Na + Cl2 → 2NaCl, the total mass of the products (2NaCl) will be:
(2Na) + (2Cl) = (2 x 22.99 amu) + (2 x 35.45 amu) = 45.98 amu + 70.90 amu = 116.88 amu
Therefore, the correct answer is 116.88 amu.
