Answer:
7.2 liters
Step-by-step explanation:
Find how many liters of the solution is bleach:
14% of 18 liters
= 0.14 × 18
= 2.52 liters
If the amount of bleach in the solution should be 10% then:
⇒ 10% = 2.52 liters
⇒ 100% = 2.52 × 10 = 25.2 liters
To find the amount of water that should be added, subtract the original volume of solution from the new volume of solution:
⇒ 25.2 - 18 = 7.2 liters
Therefore, 7.2 liters of water should be added to 18 liters of a 14% bleach solution so that the resulting solution contains only 10% bleach.
