Calculate the mass per cent of different elements present in sodium sulphate `(Na_(2)SO_(4))`.

Text Solution

Verified by Experts

Mass precent `= ("Mass of solute")/("Mass of solution")xx100`
Molecular mass of `Na_(2)SO_(4)=(2xx22.9g)+32.06+(4xx16.00)=142.04g`
% of Na `=(45.98xx100)/(142.04g)=32.37%`
% of S `=(32.06xx100)/(142.04)=22.57%`
% of O `= (64xx100)/(142.04)=45.06%`

Comprehension # 1 Potash is any potassium mineral that is used for its potassium content. Most of the potash produced in the United States goes into fertilizer. The major sources of potash are potassium choride (KCI) and potassium sulphate (K_(2)SO_(4)) . Potash production is often reported as the potassium oxide (K_(2)O) equivalent or the amount of K_(2)O that could be made from a given mineral.
