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
<span>x = 1.5 ounces of Chlorine</span>
