Question 491878
How much water must be evaporated from 32 pounds of a 4% solution of salt and water to make the result a solution that is 6% salt
**
let x = pounds of water that must be evaporated from 32 lbs of 4% solution
4%(32)=6%(32-x)
1.28=1.92-.06x
.06x=1.92-1.28=.64
x=10.67 lbs of water
ans:
10.67 pounds of water that must be evaporated from 32 lbs of 4% solution of salt and water to make the result a solution that is 6% salt
