Determining the Concentration of a Solution: Beer’s Law
A solution has a concentration of 1.25g/L. What is its concentration in ppm? Convert the mass in grams to a mass in milligrams: 1.25g = 1.25 x 1000mg = 1250mg . Re-write the concentration in mg/L = 1250mg/L = 1250ppm . 2. A solution has a concentration of 0.5mg/mL. What is its concentration in ppm?
