@ anup 
mole concept are not confusing , they are actually the concentration terms , u have to solve it by using various formula like of molarity , molality , normality , percentage composition , mole fraction etc . 
|and the most common formula is N1V1 = N2V2 , that applies in almost all the cases . 
u need to remember all the formula of concentration terms , and then check what the ques asks and apply it accordingly . 
also , be carefull about the units .
