The antibiotic, Sulmet, is to be given to a 130-pound calf at the rate of 110 mg per pound of body weight.

1. How many mg does the calf need?

2. If Sulmet contains 245 mg of active ingredient per mL, how many mL should be administered to achieve the dose determined for the 130-pound calf?

Round your answer to 2 decimal places.

To calculate the number of mg the calf needs, multiply its weight by the rate of 110 mg per pound. For the 130-pound calf, it needs 14,300 mg. To calculate the number of mL of Sulmet to be administered, divide the dose determined for the calf by the amount of active ingredient in each mL of Sulmet. The calf should be given 58.37 mL of Sulmet.

Explanation:

To calculate the number of milligrams the calf needs, multiply its weight in pounds by the rate of 110 mg per pound. In this case, the calf weighs 130 pounds, so it needs 130 pounds × 110 mg/pound = 14,300 mg.

To calculate the number of milliliters (mL) of Sulmet to be administered, divide the dose determined for the calf (14,300 mg) by the amount of active ingredient in each mL of Sulmet (245 mg/mL). In this case, 14,300 mg ÷ 245 mg/mL = 58.37 mL. Rounded to two decimal places, the calf should be given 58.37 mL of Sulmet.
