To prepare 1500ml of hydrochlorothiazide at 10mg/ml, how many 25mg tablets are required?

To determine how many 25 mg hydrochlorothiazide tablets are needed to create a solution of 1500 mL at a concentration of 10 mg/mL, we first need to calculate the total amount of hydrochlorothiazide required for the entire solution.

The concentration of the solution is 10 mg/mL, and you need to prepare 1500 mL. Thus, the total amount of drug required is calculated as follows:

[ \text{Total amount required} = \text{concentration} \times \text{volume} ]

[ \text{Total amount required} = 10 , \text{mg/mL} \times 1500 , \text{mL} = 15000 , \text{mg} ]

Next, you need to figure out how many 25 mg tablets are necessary to provide 15000 mg. To do this, divide the total amount needed by the amount of drug in each tablet:

[ \text{Number of tablets required} = \frac{\text{total amount required}}{\text{amount per tablet}} ]

[ \text{Number of tablets required} = \frac{15000 , \text{mg}}{
