The total mass of the reactants is 58.44 amu. According to the chemical equation, 2 moles of sodium (2Na) react with 1 mole of chlorine (Cl2) to form 2 moles of sodium chloride (2NaCl).

To find the total mass of the products, we can calculate the molar mass of sodium chloride (NaCl).

The molar mass of sodium (Na) is approximately 22.99 amu, and the molar mass of chlorine (Cl) is approximately 35.45 amu.

The molar mass of sodium chloride (NaCl) is the sum of the molar mass of sodium and chlorine, which is 22.99 amu + 35.45 amu = 58.44 amu.

Since 2 moles of sodium chloride are produced in the reaction, the total mass of the products is 2 moles x 58.44 amu/mole = 116.88 amu.

Therefore, the correct answer is 116.88 amu.
