In the crystalline solid MSO_(4).nH_(2)Oof molar mass 250 g mol^(-1), – InterviewSolution

1.	In the crystalline solid MSO_(4).nH_(2)Oof molar mass 250 g mol^(-1), the percentage of anhydrous salt is 64 by weight. The value of n is
Answer» 2 3 5 7 Solution :Mass of anhydrous `MSO_(4)` salt `=64/100 xx 250 = 160` g/mole TOTAL mass of `H_(2)O` in `MSO_(4).nH_(2)O = 250-160 = 90` g/mole Therefore, the value of N `=90/18 =5`
