Question

A bleach disinfecting solution is mixed at a 1:5 ratio (bleach to water). If the solution has 500 mL of distilled water, how many milliliters of bleach is required? Round your final answer to 1 decimal place if necessary.

Answer 1

100 mL

Step-by-step explanation:

Given that:

Ratio of bleach to water = 1 : 5

Quantity of distilled water = 500 mL

Let the quantity of bleach and water in the solution be x and 5x respectively.

Since quantity of water is 500 mL, equate 5x with 500 and find x.

`\begin{gathered} 5x=500 \\ x=(500)/(5)=100 \end{gathered}`

So, the quantity of bleach required = 100 mL.
