Hey buddy,
● Answer-
V' = 4.807 kcal
● Explaination-
# Given-
W = 10 g
V = 3.7 eV
# Solution-
Number of moles = Sample weight / molecular weight
Number of moles = 2/35.5
Number of moles = 0.05634
Electron affinity,
V' = no of moles × V
V' = 0.05634×3.7
V' = 2.085 eV
Converting into kcal-
V' = 2.085×23.06
V' = 4.807 kcal.
4.807 kcal energy is released when 10 g of Cl2 is converted to Cl- ion.
Hope this is useful...
