The molarity and molality of a solution of sulphuric acid are 11.07 and 21.91 respectively. The density of the solution in g/ml is

Explanation

Molality (m), molarity(M), density (d) and gram molecular weight of solute (100 for heptance) are related as
`m=(Mxx1000)/(1000d-MxxGMW)(or)21.3=(11.01xx1000)/(1000d-11.01xx100)`
Density of solution` =1.618g cc^(-1)`
