Normally and molarity: An aqueous solution contains `9.50g` of barium hydroxide in `200 mL` of solution. Calculate (i) the molartiy and (ii) the normally of the solution. trategy : Convert grams of `Ba(OH)_(2)` to  moles  of `Ba(OH)_(2)` and then calculate  molarity. Becuase each formula unit of `Ba(OH)_(2)` furnishes two `Oh` ions, 1 mol `Ba (OH)_(2) = 2 eq Ba(OH)_(2)`. Thus, normally is twice of molarity for `Ba (OH)_(2)` solution.
