The vapour pressure of a solution containing 2g of an electrolyte BA in 100g of water, which dissociates in one `B^(+) and "one" A^(-)` ion in water is 751 at `100^(@)C`. Calculate degree of ionization of BA if its mole wt is 56.

Explanation

To solve the problem step by step, we will follow the given information and apply the relevant formulas.

### Step 1: Gather the Given Data
- Vapor pressure of the solution (P_solution) = 751 mm Hg
- Vapor pressure of pure water (P°_solvent) = 760 mm Hg
- Mass of electrolyte BA = 2 g
- Mass of water = 100 g
- Molecular weight of BA (M_BA) = 56 g/mol
