The appropriate mixing ratio for a solution to kill blood borne pathogens is 1 part chlorine to 10 parts water if you are mixing a solution in a spray bottle with 15 ounces of water how much chlorine do you need to add for the correct ratio

To solve this problem, all we have to do it to make use of the principle of ratio and proportion. We are given the following ratio:

1 part Chlorine / 10 parts Water

Now to determine the amount of chlorine needed for 15 ounces of water, all we have to do is to use proportion. Let us say that the amount of Chlorine needed is x, therefore:

1 part Chlorine / 10 parts Water = x / 15 ounces Water

so,

1 / 10 = x / 15

Therefore calculating for x:

x = 15 / 10

x = 1.5 ounces of Chlorine
