How many liters of a 20 percent alcohol must be mixed with 40 liters of a 90 percent solution to get a 60 percent solution?
Let L be the liters to be added. Then (L) x (0.2) + (40 x 0.9) = (L + 40) x 0.6 0.2L + 36 = 0.6L + 24 36 - 24 = (0.6 - 0.2)L 12 = 0.4L L = 12/0.4 = 120/4 = 30 Liters

How do you calculate percent changes for example if I had 120 liters of 20 percent solvent and if I where to distill it to 90 percent how many liters would I have left and please add how you do it?
The solvent is a 20% solution, therefore 20% of the solution is the solvent, 80% is the solute; thus: solvent: 20% of 120 L = 20/100 x 120 L = 24 L Assuming none of the solvent is lost during the distillation, then the final solution is 90% solvent and 10% solute. Previously (above) it has been worked out that there are 24 liters of solvent, which now represents 90% of the (new) whole, so: 90% of the_new_whole = 24 L → 90/100 x the_new_whole = 24 L → the_new_whole = 24 L ÷ 90/100 = 24 L x 100/90 = 262/3 liters ≈ 26.667 liters of the final solution.
