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