Water and ethanol, CH₃CH₂OH(l), are miscible, that is, they can be mixed in all proportions. However, when these liquids are mixed, the total volume of the resulting solution is not equal to the sum of the pure liquid volumes, and we say that the volumes are not additive. For example, when 50.0 mL of water and 50.0 mL of CH₃CH₂OH(l), are mixed at 20 °C, the total volume of the solution is 96.5 mL, not 100.0 mL. (The volumes are not additive because the interactions and packing of water molecules are slightly different from the interactions and packing of CH₃CH₂OH molecules.) Calculate the molarity of CH₃CH₂OH in a solution prepared by mixing 50.0 mL of water and 50.0 mL of CH₃CH₂OH(l) at 20 °C. At this temperature, the densities of water and ethanol are 0.99821 g/mL and 0.7893 g/mL, respectively.
