Question
Calculate the molecular mass of chloroform (CHCl3). (Atomic masses : C = 12 u ; H = 1 u ; Cl = 35.5 u)
Solution
Given:
Atomic mass of C = 12 u
Atomic mass of H = 1 u
Atomic mass of Cl = 35.5 u
Therefore, molecular mass of CHCl3 can be calculated as follows:
(1 × 12) + (1 × 1) + (3 × 35.5) = 119.5
Hence, molecular mass of chloroform is 119.5 u.
