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

Molecular formula of glucose is C₆H₁₂O₆. 

Atomic mass of C = 12u 

Atomic mass of H = 1u 

Atomic mass of O = 16 u 

Molecular mass = (6 × 12) + (12 × 1) + (6×16) = 180u
