Question
Calculate the molecular masses of the following compounds :
Ethanol, C2H5OH
Solution
Given:
Atomic mass of C = 12 u
Atomic mass of O = 16 u
Atomic mass of H = 1 u
Therefore, molecular mass of C2H5OH can be calculated as follows:
(2 × 12) + (6 × 1) + (1 ×16) = 46
Hence, molecular mass of ethanol is 46 u.
