How many tablets of clonidine 0.2mg/tablet are needed to prepare 150 ml of clonidine 0.1mg/5ml suspension?

To determine how many tablets of clonidine 0.2 mg/tablet are required to prepare 150 mL of a clonidine 0.1 mg/5 mL suspension, we start by calculating the total amount of clonidine needed for the suspension.

First, we need to establish how much clonidine is present in each 5 mL of the suspension. The concentration is 0.1 mg per 5 mL, which we can express as:

[

\text{Amount of Clonidine in 150 mL} = \left(\frac{0.1 , \text{mg}}{5 , \text{mL}}\right) \times 150 , \text{mL} = 3 , \text{mg}

]

Now that we know we need a total of 3 mg of clonidine for the suspension, we can determine how many tablets we need to achieve that dosage. Given that each tablet contains 0.2 mg of clonidine, we divide the total amount of clonidine needed by the amount per tablet:

[

\text{Number of Tablets} = \frac{3 , \text{mg}}{0.2 \
