Problema Solution
A chemist wants to create a solution that is 36% acid. How many liters of a 60% acid solution must be added to 30 liters of a 13% acid solution to obtain this 36% acid mixture?
Answer provided by our tutors
let x = liters of 60% acid solution
0.60x + 0.13*30 = 0.36(x + 30)
by solving we find:
x = 28.75 l
