Answer»

We have given compound MgSO₄ :

Molar mass of MgSO₄ = ( 24 + 32 + 64 ) = 120 g / mol.

a). % composition of MG in MgSO₄ :

= > ( 24 / 120 ) × 100 %

= > ( 1 / 5 ) × 100 %

= > 20 %

B). % composition of S in MgSO₄ :

= > ( 32 / 120 ) × 100 %

= > 0.2666 × 100 %

= > 26.67 %

c). % composition of O in MgSO₄ :

= > ( 64 / 120 ) × 100 %

= > 0.5333 × 100 %

= > 53.33 %

Hence we get required answer.
