Calculation performed

Concentration

Worked out from United States Pharmacopeia, General Notices 8.140 - percentage concentrations: % w/v is grams of constituent per 100 mL of solution and 4 other sources.

Educational calculation only. Always verify every dose against the product label and your institution's policy before administering a medicine.

How this is worked out

1 step

Concentration = 500 mg / 5 mL = 100 mg/mL = 10% w/v
