Answer 1

ANSWER.

23) Calculation of tsp of drug required.

        Formula

            Volume(ml) = Desired dose(D) /Dose in hand (H) * Quantity(Q)

     Here

       Desired dose(D) = 10 g

       Dose in hand(H) = 20 g.

            Quantity(Q) = 30 ml

As per above formula

     Volume(ml) of drug required = D/H * Q

                                                   = 10/20 * 30

                                                   = 0.5 * 30

                                                   = 15 ml

               1 tsp (teaspoon) = 5 ml.

   So

        Teaspoon(tsp) of drug required = 15/5

                                                      = 3 teaspoon per dose.
