Question
Calculate the molecular masses of the following compounds :
Ethene, C2H4
(Atomic masses : C = 12 u ; H = 1 u)
Advertisements
Solution
Given:
Atomic mass of C = 12 u
Atomic mass of H = 1 u
Therefore, molecular mass of C2H4 (ethylene) can be calculated as follows:
(2 × 12) + (4 × 1) = 28
Hence, molecular mass of ethylene is 28 u.
