How much water must be evaporated from 32 ounces of a 4% salt solution to make a 6% salt solution?
:
Let x = amt of water required to be evaporated
;
Really a simple equation
.04(32) = .06(32-x)
1.28 = 1.92 - .06x
+.06x = 1.92 - 1.28
.06x = .64
x =
x = 10 oz to be evaporated
:
:
Check solution
.04(32) = .06(32-10.67)
1.28 = .06(21.33)
1.28 = 1.28, note the amt of salt stays the same, only the amt of water changes
