If you prepare 8 mL of hydrocortisone solution with a concentration of 5 mg/mL from 100 mg/2mL stock, how many milliliters of hydrocortisone are needed?

Required volume(8 ml) * Required Concentration(5mg) = 40mg hydrocortisone
Given concentration(100 mg/2ml) / 40mg hydrocortisone =

required volume of hydrocortisone = 0.8mL
