Question

ix) Calculate the molecular mass of the following substances
1. Oxygen molecule (O2)​

Answer 1

Answer:

32 u

Explanation:

atomic mass of oxygen is 16 u.

so, molecular mass of O2 = 16×2 u = 32u

Answer 2

Answer:

atomic mass of oxygen is 16

since, O2 = 16×2 = 32

molar mass of O2 is 32
