    Total Mass of daily drug used = 144 Kg

    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
