Question
Calculate the molecular masses of the following compounds :
Carbon disulphide, CS2
(Atomic masses : H = 1 u ; S = 32 u ; C = 12 u)
Solution
Given:
Atomic mass of C = 12 u
Atomic mass of S = 32 u
Therefore, molecular mass of CS2 can be calculated as follows:
(1 × 12) + (2 × 32) = 76
Hence, molecular mass of carbon disulphide is 76 u.
