Question

How many litres of water will have to be added to 1125 litres of the 45 % solution of acid so that the resulting mixture will contain more than 25% but less than 30 % acid content?

Answer 1

Answer:

(0.45)(1125) = 506.25. There are 506.25 litres of acid in the solution. Since we will be adding only water, the litres of acid will not change.
