Answer:
Faraday's constant will be smaller than it is supposed to be.
Explanation:
If the copper anode was not completely dry when its mass was measured, mass of the copper must be heavier than it should have been. Hence, the calculated Faraday’s constant would be smaller than it is supposed to be since when calculating Faraday’s Constant, the charge transferred is divided by the moles of electrons.
Answer:
The new pressure of the gas comes out to be 400 KPa.
Explanation:
Initial volume of gas = V =
Initial pressure of gas = P = 120 KPa
Final volume of gas = V' =
Assuming temperature to be kept constant.
Assuming final pressure of the gas to be P' KPa

New pressure of gas = 400 KPa
