wariber [46]

Answer:

The correct answer is 7.5 ml

Explanation:

If we divide a concentration (in mg/ml) into a mass (in mg) we obtaine a volume (in mL). Thus, in order to calculate the mililiters of medicine which contain 150 mg of the active, we have to only divide mass (150 mg) into the concentration of active ingredient as follows:

mL = \frac{150 mg}{20 mg/mL}= 7.5 mL
