Two solutions of different concentrations of acid are mixed creating 40 ml of a solution that is 32% acid. one-quarter of the solution is made up of a 20% acid solution. the remaining three-quarters is made up of a solution of unknown concentration, c. which equation can be used to determine c, the unknown concentration? 30c + 10(0.2) = 40(0.32) (c) + (0.2) = 40(0.32) (c)( (0.2)) = 40(0.32) 30(c)(10(0.2)) = 40(0.32)
