lb equals 12.654 g kg

    Volume of each dose (1 tbsp) = 15 mL.
    Number of dose per day (BID) = 2
    Numder of days the bottle is supplied for (6 days) = 6
    Therefore, volume of the medication in the bottle = 15 × 2 × 6 mL = 180 mL.
    Given that, there is 1054.5 mg drug contained in each dose (1 tbsp). Therefore, we can write:

    `(1054.5\quad mg)/(15\quad mL)=x/(180 \quad mL)`
    `therefore x = 12654 \quad mg = 12.654\quad g` Ans.
