Dimensional analysis method
by: Brad Wojcik, Pharm D

You are starting off with hours and have to end up with mg or g (we can use either one). The first step is to calculate how many g are in the 500 mL. 500ml(0.5g/100mL)= 2.5 g. Now you have a given, a bunch of ratios and the units of the answer. Just line everything up so that the units cancel out and you end up with g

the strength is 0.5% (0.5g/500mL). you used 2.5% (2.5g/500mL)
