An electrolysis apparatus was set up connecting three cells in a series. In one cell 45.37 mL of hydrogen gas were formed at the cathode. The temperature was 21.5° C and the pressure in the buret was determined to be 753.8 mm Hg (determined by subtracting the pressure due to the mass of water in the buret from the barometric pressure). The vapor pressure of water at this temperature is 0.0253 atm.
a. Moles of Hydrogen (H2) gas formed (PV = nRT)
b. Number of Faradays (= moles of electrons) that passed through the cell
