An aqueous solution containing 1.0 g ephedrine in 20.0 mL solution is said to be: 0.50% ephedrine (mass/vol) 0.050% ephedrine (mass/vol) 20.0% ephedrine (mass/vol) 5.0% ephedrine (mass/vol) 1.0% ephedrine (mass/vol)

Step 1
Given: - Mass of ephedrine = 1.0 g - Volume of solution = 20.0 mL Mass/volume percentage = (mass of ephedrine / volume of solution) * 100 Mass/volume percentage = (1.0 g / 20.0 mL) * 100 Mass/volume percentage = 0.05 * 100 Mass/volume percentage = 5% ** Show more…
