B. 800 gm
C. 1.8 gm
D. 180 mg
I believe its D.180MG
To determine how much codeine is needed to prepare 120 ml of a cough syrup with a codeine concentration of 15 mg/ml, you need to multiply the volume of the cough syrup (120 ml) by the desired codeine concentration (15 mg/ml).
The calculation can be done as follows:
120 ml x 15 mg/ml = 1800 mg
Therefore, the correct answer is D. 180 mg.
