An oleum sample is labelled as 118%, Calculate
(i) Mass of `H_(2)SO_(4)` in 100 gm oleum sample
(ii) Maximum mass of `H_(2)SO_(4)` that can be obtained if 30 gm sample is taken
(iii) Composition of mixture (mass of components) if 40 gm water is added to 30 gm given oleum sample

Answer

(i) 20gm; (ii) 35.4 gm; (iii) `H_(2)SO_(4) = 35.4 gm, H_(2)O = 34.6 gm`
