lb equals 37 Kg kg

PPM is the number of grams present per 1 million (1,000,000) grams of the preparation or solution or mixture.
67.1 PPM means, there is 67.1 g of drug present in each million (1,000,000) g of the preparation.
Weight of drug = 2482.7 mg.
Converting it to grams =2482.7/1000=2.4827 g.
Therefore, we can write:
(67.1 \quad g)/(1,000,000\quad g)=(2.4827\quad g)/x therefore x = 37000 g.
Converting g into Kg:
=37000/1000=37 Kg. Ans.
