Question 794648: A chemist has two solutions, one is 30 percent alcohol, and the other is 90 percent alcohol. How much of each solution should be mixed together to make 400 liters of solution that is 54 percent alcohol?
Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
The chemist should do this:
L = 30%
T = 54%
H = 90%
M = 400 ml.
u = unknown ml. volume of L
v = unknown ml. volume of H
and
and solve for u and v.
The chemist can then use the same formulas for any two-part mixture for other materials and with other given values.
