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?
6 30c + 10(0.2) = 40(0.32)
02()+ . (0.2) = 40(0.32)
O
(C)
(0.2)) = 40(0.32)
O 30(c)(10(0.2)) = 40(0.32)
