The doctor prescribes 150 ml of amoxicillin 250 mg/5ml but switches to chewable tablets. How many tablets are needed for the same dosage?

To determine the number of chewable tablets needed to fulfill the prescribed dosage of amoxicillin, we first need to calculate the total amount of amoxicillin required.

The prescription calls for 150 ml of a solution that contains 250 mg of amoxicillin per 5 ml. To find out how much amoxicillin is in 150 ml, we first calculate the concentration in mg per ml:

250 mg / 5 ml = 50 mg/ml

Now, we can find the total amount of amoxicillin in 150 ml:

50 mg/ml x 150 ml = 7500 mg

Next, we need to know how much amoxicillin is in each chewable tablet. For this example, let's assume each chewable tablet contains 250 mg of amoxicillin, which is a common dosage for chewable formulations.

To find out how many tablets are needed to achieve the total of 7500 mg of amoxicillin, we divide the total amount needed by the amount in each tablet:

7500 mg ÷ 250 mg/tablet = 30 tablets

Thus, 30 chewable tablets are required to match the original dosage of 150 ml of the liquid amoxicillin.
