sodium reacts with chlorine to form the compound sodium chloride, or salt. The chemical formula below shows how the two elements compound into a compound.

Question

2Na + Cl2 --> 2NaCl

If the total mass of the reactants is 58.44 amu, what will be the total mass of the products?

a. 58.44 amu
b. 29.22 amu
c. 116.88 amu
d. 60 amu

Answer 1

In a chemical reaction, the law of conservation of mass states that the total mass of the reactants must equal the total mass of the products. Therefore, if the total mass of the reactants is 58.44 amu, the total mass of the products must also be 58.44 amu.

So, the correct answer is:

a. 58.44 amu
