Let$$s check whether the compositions given in each part are correct. Assume that we only know mol$\%$ and volume $($or mass$)$ of one component $($CaCl$2$ for Part A$,$ and IPA for Part B and C$),$ calculate required volumes for water in Part A and B$,$ and hexane in Part C$.$You do not have to show calculations for $0\%$ and $100\%.$ Find density and molecular weight of chemicals online.
