A cellulose solution contains 5% cellulose by weight in water. It is to be diluted to 4.0 % using a 1% solution of cellulose in water. Determine the kilograms of 1% solution required to dilute 100 kg of the 5% solution.

Answer 1

Let x =kg of 1%.
(100 kg*5) = (x*1) = (100+x)*4
Solve for x.

Answer 2

25%
