gogolik [260]

Answer:

4 grams

If in an experiment, we have 4g of reactants, the mass of the products will also be 4g.

According to this law,

  "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".

If:

      A + B →  C

         4g        4g

mass of A and B must be equal to the mass of the product according to the law of conservation of mass.
