al alcohol solution contains 35.0g of propanol (C3H7OH ) and 150.0g of ethanol . Calculate the mass percent of propanol : 45.6, 18.9, 25.3. 67.9, 81.1

Solutions

Expert Solution

mass of percent of propanol = propanol mass x 100 / total mass

                                             = 35.0 x 100 / 35.0 + 150.0

                                              = 18.9 %

answer : 18.9 %
