30 mL of a 60 mg/5 mL elixir contains 360 mg of the drug.
To calculate this, you multiply the volume of the elixir (30 mL) by the concentration of the drug per mL (60 mg/5 mL), which simplifies to 60 mg/mL when you divide the numerator and denominator by 5.
So, the calculation is:
30 mL * (60 mg / 5 mL) = 30 mL * 12 mg/mL = 360 mg
