Question

The molecular formula of glucose is C6H12O6. Calculate its molecular mass. (Atomic masses : C = 12 u ; H = 1 u ; O = 16 u)

Answer 1

Given:

Atomic mass of C = 12 u

Atomic mass of H = 1 u

Atomic mass of O = 16 u

Therefore, molecular mass of C₆H₁₂O₆ can be calculated as follows:

(6 × 12) + (12 × 1) + (6 ×16) = 180

Hence, molecular mass of glucose is 180 u.
