Step-by-step explanation
The mass percent of , that is , represents that of is present in of water.
The number of moles of is calculated by the formula,
(considered as equation 1)
Where,
-
is the mass of present in solution.
-
is the molar mass of .
The actual number of moles of present in the solution is calculated by the formula,
(considered as equation 2)
Where,
-
is the Van’t Hoff factor of .
-
is the number of moles of .
The given compound is given to be completely dissociable. The Van’t Hoff factor of is .
