A mole is not a unit of weight. A mole tells you how many atoms or molecules you have of a given substance (that number being 6.023 x 1023 which is also known as Avogadro's number). So, depending upon what substance you are dealing with, the weight can vary tremendously. A mole of uranium is much heavier than a mole of hydrogen.

What is the final concentration of cl ion when 250 ml of 020 M cacl2 solution is mixed with 250 ml of 040 M kcl solution?
Start with CaCl2. 250ml of 0.20M solution will give (0.2/1000)*250 moles = 0.05 moles. However, CaCl2--> Ca2+ + 2Cl- (1:2 reaction) so 0.05moles of CaCl2 will give 2* 0.05 moles cl ions =0.1moles. KCl will give (0.4/1000)* 250 moles =0.1 moles Since KCl--> K+ + Cl- (1:1 reaction) so 0.1 moles KCl will give 0.1 moles Cl ions. Add the 2 together so 0.1moles + 0.1 moles = 0.2 moles in total.
