In a chemical reaction to molecules with a total mass of 76 amu react to form a single molecule. What is the mass of the molecule that is formed?

A 38 amu
B 152 amu
C 76 amu
D 228

1 answer

The mass of the molecule that is formed in the reaction is equal to the sum of the masses of the two reacting molecules.

Total mass of the reacting molecules = 76 amu

Therefore, the mass of the molecule that is formed is 76 amu.

C 76 amu
