Question

How many liters of water should be added to 18 liters of a 14% bleach solution SO that the resulting solution contains

Answer 1

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.
