mL
Explanation & Rationale
Step by step calculation Determine the dosage required: 0.05 g Convert grams to milligrams: 0.05 g×1000 mg/g=50 mg Determine the concentration available: 20 mg/mL Use the formula: Volume (mL)=Required dose (mg)/Concentration (mg/mL) Volume (mL)=50 mg/20 mg/mL Calculate the volume: Volume (mL)=2.5
