According to the Law of

Conservation of mass, if two

atoms, with atomic masses of 2

AMU and 5 AMU were combined

in a chemical reaction, what

would be the mass of the final

product?

A. 7 AMU

B. 10 AMU

C. 16 AMU

A) 7 AMU

Explanation:

The Law of Conservation of mass states that during a reaction mass is neither gained nor lost. So by reacting the two products together, the final mass should be the addition of their two constituent masses (2 and 5)
