Calculate the percentage composition of ...

Calculate the percentage composition of magnesium sulphate . [Give : Atomic massess Mg = 24, S = 32, O = 16].

Text Solution

Verified by Experts

Molecular formula : `MgSO_(4)`
Molecular mass `= 1 xx 24 + 1 xx 32 + 4 xx 16 = 120`
Gram molecular mass = 120 g
Percentage of `Mg = (24)/(120) xx 100 = 20.00`
Percentage of `S = (32)/(120) xx 100= 26.66`
Percentage of `O = (64)/(120) xx 100 = 53.33`
