A 12-pound cat is prescribed amoxicillin at 5 mg/kg twice a day for seven days. The oral medication has a concentration of 50 mg/mL. Approximately how many mLs will the cat need per day?

For this case we have to take into account the following conversion:

1 lb = 453.59 g

The weight of the cat in grams is:

(12) * (453.59) = 5443.08 grams

The weight of the cat in kilograms is:

(5443.08) * (1/1000) = 5.44308 Kg

Then, we calculate the number of milligrams needed:

amoxicillin at 5 mg / kg twice a day for seven days:

(2) * (7) * (5) = 70 (mg / (kg * day))

The number of milligrams per day is:

5.44308 * (70) = 381.0156 mg / day

Finally the number of mLs is:

(381.0156) / (50) = 7.62 mLs / day

Answer:

the cat will need 7.62 mLs per day
