A12-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
 
 the cat will need 7.62 mLs per day
