Question: Hydrogen peroxide in dilute concentrations can be analyzed by differential pulse polarography. Calibration led to the following relationship nA la = (7.002 107) [H0]

Hydrogen peroxide in dilute concentrations can be analyzed by differential pulse polarography. Calibration led to the following relationship nA la = (7.002 107) [H0] - 1.500 nA Find the hydrogen peroxide concentration in ppb for an unknown that gave a peak current of 300.0 nA.
