lb equals 2987.6 mg kg

    61.6 PPM means, there is 61.6 g of drug in each 1,000,000 g of the mixture.
    The total weight of the preparation = 48500 grams. Therefore, we can write:
    `(61.6 \quad g)/(1,000,000\quad g)=x/(48500\quad g) therefore x = 2.9876` g.

    Now, this g unit has to be converted to mg.
    `(1000\quad mg)/(1\quad g)= y/(2.9876\quadg) therefore y = 2987.6` mg Ans.
