Benji, a 12 kg border terrier, requires daily injections of ampicillin 15% for 3 days. the dose rate is 7.5
mg/kg. how many ml per injection does benji require? i just need to know how to set the problem up, using dimensional analysis.

The answer is:

Benji requires 90mL per injection.

From the statement we know that dog's weight is 12 kg, and daily injections are required for 3 days, the dose rate is 7.5 mg/kg, so we need to calculate how many mL per injection does Benji require.

We have that:

If the dose rate is 7.5 mL per each Kg, how many mL are required for 12 Kg? We can set it up using the following relation:

Hence, we have that there are needed 90 mL per injection.

Have a nice day!
