Weight of NaCl=58.44g
Weight of AgNO3=169.87g
Weight of AgCl=143.32g
Weight of NaNO3=84.99g
Therefore, the weight of reactants and products are-
NaCl+AgNO3→AgCl+NaNO3
(23+35.5) +(108+14+48) →
(23+14+48) + (108+35.5)
58.5 + 170 → 85 + 143.5
228.5g → 228.5g
Thus, the weight of reactant = weight of product which is 228.5g
