Question

A doctor orders 2 tablets of amoxicillin per day for 11 days. If each tablet contains 375 mg of amoxicillin, how many mg of amoxicillin is given to the patients over those 12 days?

Dimensional analysis only

Answer 1

The total amount of amoxicillin given to the patient over 12 days is 8,250 mg.

Answer 2

To find the total amount of amoxicillin given over 11 days, we can use dimensional analysis.

Start by identifying the known quantities: 2 tablets per day and 375 mg per tablet.

Next, identify the unknown quantity: the total amount of amoxicillin given over 11 days (in mg).

Write the equation using the known quantities and the unknown quantity:

(2 tablets/day) x (375 mg/tablet) x (11 days) = unknown quantity

Use the units to cancel out units and get the final result:

2 x 375 x 11 = 8250 mg

So, over 11 days, the patient will receive 8250 mg of amoxicillin.
