Question

In a compound carbon and hydrogen are present in a ratio 3 : 1 by mass. Find out the molecular formula of the compound. (Atomic mass. of C= 12 u, Atomic mass of H = 1 )

Answer 1

Answer:CH3

Explanation:

Answer 2

Answer:

Atomic mass of hydrogen = 1 a.m.u.

Atomic mass of Sulphur = 32 a.m.u.

Thus, the molecular mass of hydrogen sulphide, which contains two atoms of hydrogen and one atom of sulphur is = 2 — 1 + 1 — 32 = 34 a.m.u.
