Answer to Question #34884 in Chemistry for Tammie

Question

A 50.0 % kg mixture of salt and water is 15.0 % (by mass) salt. Give the mass of salt and water in the mixture. I took 50.o x 15.0 then divided by 100 and got 7.5. Then I subtracted 7.5 from 100 and got 92.5. I would appreciate the help. I am confused.

Answer 1

Salt mass = 50*0.15 = 7.5
Water mass = 50 - 7.5 = 42.5
