Question 279075: how much soap is needed to make 10 liters of a 20% soap solution
Answer by oberobic(2304)   (Show Source):
You can put this solution on YOUR website! Volume = 10 liters
Desired solution is 20% soap, so we assume that 80% is pure water.
Assuming we are measuring volumes, then the amount of pure soap in 10 liters of 20% soap is .2*10 = 2 liters of pure soap.
That means we add 8 liters of pure water to arrive at 10 liters.
