Because it ionizes into Na+ and Cl-, thus ONE mole or molecule of NaCl produces TWO moles or molecules, namely Na and Cl, thus i (the van't Hoff factor) is 2.

This value is 36.
NaCl has not 2 in the formula unit.
This value is approx. 36.
13g Cl2 * (1mol cl / 34.45 ) * (2 mol / 2 mol) * (58.44g NaCl / 1 mol NaCl) = 22g NaCl
NaCl
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58 grams 25.0 grams NaCl / (58 grams) = .431* moles NaCl *approximation
That refers to a mixture consisting of 2/100 of sodium chloride (salt) and 98/100 of something else (usually water).
This value is 36,79 kJ/mol.
molten NaCl and An aqueous solution of NaCl will be conducting due to the presence of free ions in these.
Two methods of preparation in laboratory:- 2 Na + Cl2 = 2 NaCl- NaOH + HCL = NaCl + H2O
