30 % by weight solution of means 30g of is dissolved in 100g of solution.
Let volume of each solution mixed =100 ml
 Therefore, total volume of solution = 200 ml
Wt. of  in 30 % solution = g
 
Wt. of  in 70 % solution =  =112.7 g
 Total wt. of    = 33.84 +112.7 =146.54 g
 
 
 
Now,        Molarity = 
                        =
