What is the correct relationship between the observed molecular mass and the theoritical molar mass of NaCl?

Option: 1

\mathrm{Observed\ molar\ mass= \frac{Theoretical\ molar\ mass }{2} }


Option: 2

\mathrm{Observed\ molar\ mass= Theoretical\ molar\ mass}


Option: 3

\mathrm{Theoretical\ molar\ mass= \frac{Observed\ molar\ mass }{2} }


Option: 4

\mathrm{Theoretical\ molar\ mass= \frac{1}{Observed\ molar\ mass } }

NaCl dissociates as 

\mathrm{NaCl \longrightarrow Na^+ + Cl^-}

Thus, effective number of particles formed from 1 particle of NaCl is 2.

Thus, 

\mathrm{Observed\ molar\ mass= \frac{Theoretical\ molar\ mass }{2} }

Hence, the correct answer is Option (1)
