Answer #1

ANSWER.

* Calculation of amount(ml) of drug required.

Formula

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

Here

Desired dose(D) = 250 mg.

Dose in hand(H) = 500 mg.

Quantity(Q) = 1 ml.

As per above formula

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

= 250/500 * 1

= 0.5 * 1

= 0.5 ml.
