0.7 mL of Seconal corresponds to how many mg, given a 50 mg/mL concentration?

The key idea is using concentration to convert volume to mass. Since the solution has 50 mg per mL, multiply the volume by the concentration: 0.7 mL × 50 mg/mL = 35 mg. So the dose is 35 mg. For context, 0.5 mL would be 25 mg, 1 mL would be 50 mg, and 1.4 mL would be 70 mg, illustrating how the amount scales with volume.
