lb equals 23000 g kg
-
PPM is the number of grams present per 1 million (1,000,000) grams of the preparation or solution or mixture.
75.9 PPM means, there is 75.9 g of drug present in each million (1,000,000) g of the preparation.
Weight of drug = 1.7457 g.
Therefore, we can write:
`(75.9 \quad g)/(1,000,000\quad g)=(1.7457\quad g)/x therefore x = 23000` g. Ans.
