Step-by-step explanation:
NO = TS
- 20 = 3x-7
- 20+7 = 3x
- 27 = 3x
- 27/3 = x
- 9 = x
Hope this helps you.
We have 89 ounces of 47% iodine.
We will add "x" ounces of 14% iodine to get a 29% iodine solution.
89 * .47 + .14x = .29 * (89 + x)
41.83 + .14x = 25.81 + .29x
16.02 = .15x
x = 106.80
So, we must add 106.80 ounces of 14% iodine to get a 29% iodine solution.
(for a total of 195.80 ounces)
