The coductivity of a solution may be take to the directly proportional to the total concentration of the charge carriers (ions) present in it in many cases. Using the above fid the percent decrease in conductivity (k) of a solution of a weak monoacidic base BOH when its 0.1 M solution is diluted to double its original volume `(K_(b)=10^(-5)` for BOH) (take `sqrt(50)=7.07`) (mark the answer to nearest integer)
