Question

According to a magazine, a cleaning solution of 5% bleach will remove mildew from a shower or tub.
How many ounces of bleach do you need to make a quart of 5% bleach solution?
Explain the method you used using complete sentences.

Answer 1

Answer:

1.6 ounces

Step-by-step explanation:

5% bleach solution means,

100 units of solution contains 5 units of bleach.

So, one quart of bleach solution contains 5/100 quarts =0.05 quarts of bleach.

Now, we know that,

1 US liquid quart ≡ 32 US fluid ounce

Hence, 0.05 quarts of bleach = 0.05×32 ounces of bleach

⇒ 0.05 quarts of bleach = 1.6 ounces of bleach

Therefore, one quart of bleach solution contains 1.6 ounces of bleach.
