Calculate the molecular masses of the following compounds: (a) Hydrog

1.	Calculate the molecular masses of the following compounds: (a) Hydrogen sulphide, H2S (b) Carbon disulphide, CS2 (Atomic masses: H = 1 u, S = 32 u, C = 12 u)
Answer» (a).Molecular mass of hydrogen sulphide (H₂S) = 2xH + 1xS = (2+32) u = 34u (b). Molecular mass of Carbon disulphide (CS₂) = 1xC + 2xS = (12+2 x 32) u = 76 u

Calculate the molecular masses of the following compounds: (a) Hydrogen sulphide, H2S (b) Carbon disulphide, CS2 (Atomic masses: H = 1 u, S = 32 u, C = 12 u)

Answer»

(a).Molecular mass of hydrogen sulphide (H₂S)

= 2xH + 1xS = (2+32) u = 34u

(b). Molecular mass of Carbon disulphide (CS₂) = 1xC + 2xS = (12+2 x 32) u = 76 u
