Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

What is the volume (in liters) ofa .20M solution that contains .30 moles of Na2SO4 dissolved in it ? Making Dilutions: Chemists often use more concentrated solutions to make more dilute solutions. The number of moles of solute does not change when a soultion is diluted. Number of moles before dilution = Number of moles after dilution Since moles Molarity (M) x liters ( V), then : M1 x V1 M2 x V2 %D Example : How would you prepare 100 ml of .4OM MGSO4 form a solution of 2.0 M MgSO4 ?
