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.
