How many liters of chlorine gas measured at STP would be pro

How many liters of chlorine gas, measured at STP, would be produced by the electrolysis of molten sodium chloride using a current of 3.50 amperes for 46 minutes? (Cl: 35.453 g/mol)

Solution

2Cl- ---> Cl2 + 2e-

q=i*t = 9450 coulomb

n=q/f = 0.098 moles e-

so mole of Cl2 = 0.098/2 = 0.049 moles

at STP 1 mole = 22.4L

so volume of CL2 = 1.0976 L
