Answer: 1.5 ounce
Step-by-step explanation:
Given: The appropriate mixing ratio for a solution to kill blood borne pathogens is 1 part chlorine to 10 parts water .
Thus, 10 parts of water in a spray bottle = 15 ounces
Now, 1 part of water in a spray bottle = [tex]\frac{15}{10}[/tex]
Thus, 1 part of water in a spray bottle =1.5 ounces
As we need to mix 1 part of chlorine and 1 part of spray .
Therefore, the amount of chlorine we need to add for the correct ratio = 1.5 ounce.
