How many liters of pure water must be evaporated from 60 liter of a 3 percent salt water solution to produce a solution that will be a 5 percent salt water solution?
Well, it's been awhile since I've done this but my answer would be 24 liters must evaporate to make a 5% solution. 60 * .03 = 1.8 ~ That's what you have. The 1.8 is how many liters of salt you have. 60 = x ~ Replace 60 with x. x * .05 = 1.8 ~ The percentage of salt is now 5 but you still have 1.8 liters. 1.8/.05=36 ~ algebra... 60 - 36 = 24 ~ Total minus how much will remain gives you the total that must evaporate. I know you could have followed them easily enough without the notes. They were more for me so I knew I'd done it correctly. :-) Hope it's right and .
