Rubbing alcohol sold in stores is aqueous 2-propanol, CH,CHOHCH₂(aq). Rubbing alcohol is available in concentrations of 70.% and 91% 2-propanol by volume. To make 100. mL of 70.% aqueous 2-propanol, 70. mL of 2-propanol is diluted with enough water to produce a total volume of 100. mL. In a laboratory Investigation, a student is given a 132-mL sample of 91% aqueous 2-propanol to separate using the process of distillation. Determine the maximum volume of 2-propanol in the 132-mL sample.
