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)

Academic Chemistry NCERT Class 9

(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
