Number of units of Penicillin ordered = 700,000 units
The vial of penicillin is labeled as 250000 units/ cc, which means 250000 units of penicillin has 1 cc volume .
volume of 1 unit of penicillin = 1 / (250000) cc = 4 * 10-6 cc
Volume of 700,000 units of penicillin that is ordered = volume of 1 unit of penicillin * number of units
= (4*10-6)* (700,000) = 2.8 cc
by unit conversion : 1 cc = 1 cm3 = 1 mL
Volume of 700,000 units of penicillin that is ordered in mL = 2.8 * 1 mL = 2.8 mL
