Question

Part A A doctor orders 2.0 mg of morphine. The vial of morphine on hand is 30 mg per 6.0 mL How many milliliters of morphine should you administer to the patient? Express your answer to two significant figures and include the appropriate units.​

Answer 1

To solve this problem, we can use a proportion:

(2.0 mg) / (x mL) = (30 mg) / (6.0 mL)

where x is the unknown number of milliliters we need to administer.

To solve for x, we can cross-multiply and simplify:

(2.0 mg) * (6.0 mL) = (30 mg) * (x mL)

12 = 30x

x = 12/30 = 0.4 mL

Therefore, we should administer 0.4 mL of morphine to the patient.
