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...
