Question 616948
I have 4 oz of a 25% solution of a pesticide. I need to mix water with the pesticide to give me 32 ounces of a 0.2% solution.
How much water do I need?
How much of the 25% solution do I need to add to the water?
How did you find your answer.
**
let x=ounces of 25% solution needed
.25x=.002*32=.064
x=.064/.25=0.256 ounces
..
water needed=32-.256≈31.74 ounces
