4 grams... as by the rule of correspondence the total mass of reactants equals the total mass of the products.
Thus to produce 4 grams of table salt... 4 grams of the mixture (2Na + Cl2) is required

A) 2 grams
The sodium and chlorine form the chemical compound of sodium chloride (NaCl) in the ratio of 1:1.
The molecular mass of the chemical compound of sodium chloride (NaCl) is 58.44 g/mol.
Given the chemical formula 2Na(s) + Cl2(g) ------ 2 NaCl(s) = 2 mole of NaCl.
2 mol NaCl x 58.44 g / mol NaCl = 116.88 g NaCl.
Sodium chloride (NaCl) - Sodium chloride, also known as salt, common salt, table salt or halite, is an ionic compound with the formula NaCl, representing equal proportions of sodium and chloride.
