ANSWER.
* Calculation of rate.
Rate (ml/hr) = Volume(ml) / Time(hr).
Calculation of volume(ml)
Volume(ml) = Desired dose/Dose in hand * Quantity.
Here
Desired dose(D) = 24000 mg (24g)
Dose in hand (H) = 500 mg.
Quantity (Q) = 100 ml.
As per above formula
Volume(ml) of drug required = D/H * Q
= 24000 / 500 * 100
= 48 * 100
= 4800 ml.
Time (hr) = 24 hr.
Flow rate = Volume(ml) /Time(hr)
= 4800 / 24
= 200 ml/hr.
