**Reiny**, Thursday, January 31, 2013 at 9:48pmlet the amount boiled off be x L

amount of brine = 6 (120 g/L) = 720 g

that must stay constant

(6-x)(200 g/L) = 720 g

1200 - 200x = 720

-200x = -480

x = 2.4

2.4 L must be boiled off

check:

liquid left = 6-2.4 = 3.6 L

but there must still be 720 g in there

concentration = 720/3.6 = 200 g/L
