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 .
