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)
startfraction 3 over 4 endfraction left-parenthesis c right parenthesis plus startfraction 1 over 4 endfraction left-parenthesis 0.2 right-parenthesis equals 40 times 0.32.(c) + startfraction 1 over 4 endfraction cup.(0.2) = 40(0.32)
(c)( (0.2)) = 40(0.32)
30(c)(10(0.2)) = 40(0.32)
