Water and acetonitrile, CH3CN, are miscible (can be mixed in any proportions). However, whenwater and acetonitrile are mixed, the volumes are not additive (the total volume of the resultingsolution is not equal to the sum of the pure liquid volumes). For example, when 100.0 mL ofwater and 100.0 mL of CH3CN(l), are mixed at 20 °C, the total volume of the solution is 192.0mL,not 200.0 mL.a. Provide an explanation for this phenomenon.b. Calculate the molarity, molality and mol fraction of CH3CN in a solution preparedby mixing 100.0 mL of water and 100.0 mL of CH3CN(l) at 20 °C. The total volume of themixture is 192.0 mL and the densities of water and acetonitrile are 0.998 g/mL and 0.782g/mL, respectively, at this temperature.c. When 70.0 g H2O and 190.0 g CH3CN(l) are mixed, to resulting solution has adensity of 0.860 g/mL at 20 °C. Calculate the volumes of the pure liquid samples and thesolution, and show that the pure liquid volumes are not additive.
