This problem is providing us with the concentration of an oral suspension of amoxicillin as 200 mg / 5 mL, so the volume per dose is required, taking into account a patient must take 500 mg every six hours. At the end, the result turns out to be 12.5 mL according to:
In chemistry, we use dimensional analysis to calculate a requirement, based on given information to do so. Despite not having a formula for every problem, one can use the units a reference.
For instance, this problem asks for volume yet 200 mg / 5 mL has the volume at the bottom of the proportional factor. This means we need to flip it and then multiply by 500 mg in order to get rid of the milligrams and thus get the volume:
[tex]V=500mg*\frac{5mL}{200mg} \\\\V=12.5mL[/tex]
