ANSWER
40. Drug dosage concentration.
Formula
Volume of suspension give to the patient = Amount desired(D) / Amount on hand(H) * Quantity(Q)
Amount desired (D) = 1mg.
Amount in hand (H) = 10 mg.
Quantity = 1 ml.
Volume of suspension required for the patient = D / H * Q
= 1 / 10 *1
= 0.1 * 1
= 0.1 ml.
