greater than the total mass of the products equal to the total mass of the products equal to the mass of AgCl less than the mass of AgCl
I gave my students this multiple choice question: The equation below shows the products formed when a solution of silver nitrate (AgNO3) reacts with a solution of sodium chloride (NaCl). AgNO3 + NaCl (Reactants) -> NaNO3 + AgCl (Products) In this equation, the total mass of the reactants is

Only one answer is correct among these 4 choices:
- greater than the total mass of the products
- equal to the total mass of the products
- equal to the mass of AgCl
- less than the mass of AgCl

Could you tell me which one is correct?

equal to the total mass of the products
