A current of 0.0965 ampere is passed for 1000 seconds through 50ml of 0.1 M NaCl, using inert electrodes the average concentration of OH^– in the final solution is

Dry air was drawn through bulbs containing pure water ,then through bulbs containing a solution of 600 grams of a non electrolyte  in 360 grams of water at the same temperature and finally through a tube in which dried CaCl₂ was placed. The solution bulbs gained 1.5 gram and the dried CaCl₂ gained 2 gram.The Molecular mass of the solute is :-
