in a chemical reaction, two 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 152 amu
b 76 amu
c 228 amu
d 38 amu
To find the mass of the molecule that is formed, we need to add the masses of the two reacting molecules.
Since the total mass of the two molecules is 76 amu, the mass of the molecule that is formed will also be 76 amu.
Therefore, the correct answer is (b) 76 amu.
