Final answer:
To make a gallon of 1% chlorhexidine rinse and foot bath, you will need 0.25 gallon or 32 ounces of the 4% chlorhexidine.
Step-by-step explanation:
To make a gallon of 1% chlorhexidine rinse and foot bath, you need to dilute the 4% chlorhexidine. We can use the formula:
Initial concentration * Initial volume = Final concentration * Final volume
By substituting the given values, we get:
4% * Initial volume = 1% * 1 gallon
Now, we can calculate the Initial volume:
Initial volume = (1% * 1 gallon) / 4% = 0.25 gallon
Therefore, you will need 0.25 gallon or 32 ounces of the 4% chlorhexidine to make a gallon of 1% chlorhexidine rinse and foot bath.
