    80 grams

    Step-by-step explanation:

    Weight of 24% solution = 400 grams

    Alcohol content = 24%

    Amount of alcohol = 400*0.24 = 96 grams

    Weight of 30% solution with same amount of alcohol:

    96/0.3 = 320 grams

    The difference in weights is the other chemicals evaporated:

    400-320=80 grams
