Mixture $1$: CaCl$2+$ DI Water

Mixture $2$: IPA $+$ DI Water

Mixture $3$: IPA $+$ Hexane

Estimate the partial molar volumes of each of the three mixtures above at infinite dilution using the DATA in the table BELOW. For the mixture of CaCl$2+$ DI Water $($Part A$),$ estimate the infinite dilution of water only. For other mixtures $($Part B and Part C$),$ estimate the infinite dilution of both components.
