A gallon of Clorox bleach is labeled “5.25% sodium hypochlorite by weighs 8.3 pounds,
then how many ounces of sodium hypochlorite must be added so that the bleach will be 13% sodium hypochlorite?
Round your answer to four decimal places if necessary.
:
Change 8.3 lb to oz: 16 * 8.3 = 132.8 oz
let a = amt of this stuff required to accomplish this
:
(.0525*132.8) + a = .13(132.8+a)
6.972 + a = 17.264 + .13a
a - .13a = 17.264 - 6.972
.87a = 10.292
a =
a = 11.8299 oz of the stuff
