58.44 amu
58.44 amu

60 amu

Answer 1

According to the law of conservation of mass, the total mass of the reactants must equal the total mass of the products in a chemical reaction.

Since the total mass of the reactants is given as 58.44 amu, the total mass of the products will also be 58.44 amu.

So, the correct response is:

**58.44 amu**
