Find the % composition of hydrogen in hydrogen sulphide

5.88%

Explanation:

percent composition depends on relative atomic mass.

the percentage of component present in a compound is

(relative formula mass of component

÷

relative formula mass of compound)

⋅

100

%

the relative atomic mass of

H

(hydrogen) is

1

the relative formula mass of

H2 is 2

the relative atomic mass of S (sulphur) is 32.

2+32=34 the compound H2S is known as hydrogen sulphide.

relative formula mass of

H2÷relative formula mass of (H2S)⋅100%=2/34⋅100%=5.88% (2d.p.)
