Transcribed Image Text:

In Electrolysis and Electrolytic Cells, a DC power supply was used for applied voltage in an electrolytic cell. The average voltage difference across two 3.9-ohm resistors in series was 0.978 V for 26.0 minutes while collecting 27.7 mL H2(g) at atmospheric pressure at the cathode. a. If the barometric pressure was 755.1 mmHg, and the temperature was 21.9 oC, calculate the number of moles of H2 (gas) produced, given the vapor pressure of water at 20.0 oC is 17.5 mmHg. (1 point) b. Calculate the total charge, in Coulombs, that flowed through the circuit while the 27.7 mL H2(g) was produced.
