Question

The sulphate of an element contains 42.2% element. The equivalent weight would be

Answer 1

the eqivalent weight would be 227.488 g-mol

Answer 2

The equivalent weight of a substance is considered as the mass of the substance required to displace one gram of hydrogen or 8 grams of oxygen. Equivalent mass of the element of sulphate(X) = (Equi mass of compount+equi mass of the sulphate).

Given data :

42.2% = sulphate of the element, (100-42.2)=57.8,  57.8% of X =  48, therefore, x= 83.04, 83.04= (equi massof compound+48) = 35.04

Thus the equi mass of the element = 35.04
