Answer:
Total Mass of daily drug used = 144 Kg
Step-by-step explanation:
Total weight of the individuals =
180lbs * 10000 = 1.8 * 10^6 lbs
Since the drug is to be given 8 mg for every 100 lbs;
number of 8 mg doses = 1.8 * 10^6 / 100 = 1.8 * 10^4 doses
Total mass of the doses = 1.8 * 10^4 * 8 mg = 1.44 * 10^5 mg.
We divide the value above by 1000 to convert to Kg.
Therefore, total daily mass of drug used = (1.44 * 10^5)/1000 = 144 Kg
