Quiz from Miss Hilya


What is the weight (in g / kg ) of a fifth of a gallon of a 40 % Aqueous Alcohol solution and a weight of a fifth of good bourbon ?

Answer:

40% Aqueous Alcohol
Weight (gr)      = ρ (alcohol) x Volume Alcohol x percent of Alcohol
                        = 0,789 gr/ml x 5(3,7 L) 1000 x 40%
                        = 0,789 gr/ml x (18,5x103) ml x 40%
                        = 5.838,6 gr = 5,8386 kg
Good Bourbon
Weight (gr)    = ρ (alcohol) x Volume Alcohol x percent of Alcohol
                        = 0,789 gr/ml x 5(3,7 L) 1000 x 80%
                        = 0,789 gr/ml x (18,5x103) ml x 80%
                        = 11.677,2 gr = 11,6772 kg
