You have 15L of 24% acid solution. How much water should you add in order to dilute the solution so that it is 8% acid?
--------
Equation:
water + water = water
0.76*15 + x = 0.92(15+x)
---------
Multiply thru by 100 to get:
76*15 + 100x = 92*15 + 92x
------
8x = 16*15
x = 30L (amt. of water to add)
