How much of other chemicals must be evaporated from 400 grams of a hand sanitizer that is 24% alcohol to strengthen it to a hand sanitizer that is 30% alcohol? Correct your answer to the nearest whole number

Mass of other chemicals to be evaporated is 24 grams.

Step-by-step explanation:

The initial mass of the hand sanitizer = 400 grams, and has an alcohol content of 24%.

mass of its alcohol content = × 400

                                            = 96 grams

mass of non-alcoholic content = 400 - 96

                                                  = 304 grams

If the percentage of alcohol is increased to 30%, then;

mass of its alcohol content = × 400

                                             = 120 grams

The mass of other chemicals to be evaporated = 120 - 90

                                                 = 24 grams
