What volume of ethanol 96 percent should be added to 500 ml of 70 percent ethanol such that when the mix is made to 2.5l with water the final conc of ethanol is 55 percent?
First calculate how much ethanol you need in the final solution. 55% X 2.5l = 1.375l Then calculate how much ethanol you already have in the solution. 0.5l X 70% = 0.35l Now take the difference between those two numbers as the extra amount needed. 1.375l - 0.35l = 1.025l Now correct for the fact that you are adding only 96% ethanol. 1.025l / 96% = 1.068l Answer: 1.068l
