How many moles of Cl₂(g)are produced by the electrolysis of concentrated sodium chloride if 2.00 A are passed through the solution for 4.00 hours? The equation for this process,the "chloralkali" process,is 2NaCl(aq)+ 2H₂O(l)$\rightarrow$2NaOH(aq)+ H₂(g)+ Cl₂(g)

The total charge passed is calculated using Q = I × t = 2.00 A × 4.00 hours × 3600 seconds/hour = 28800 C. The number of moles of electrons is Q/F = 28800 C / 96485 C/mol = 0.298 mol. Since 2 moles of electrons produce 1 mole of Cl2, the moles of Cl2 produced is 0.298 mol / 2 = 0.149 mol.
