How Do You Calculate The Number Of Moles In A Solution?
The mole, symbolized as mol, of a substance is the amount of physical quantity present in a molecule. It reduces the need of saying 6.02 x 10^23 (Avogadro’s number) when describing atoms as the word “dozen” simplifies our request of 12 pastries. The mole is used in calculating the amount of molarity, or concentration, of a given substance and eases our understanding of the ideal gas law, titration, equilibrium and other chemistry principles. Step 1 To find the number of moles in a solution, start by multiplying the molarity (M) by the volume (V in liters) of the solution. For example, if you have aluminum nitrate [AL(NO3)3] and want to determine the number of moles of nitrate (NO3) ions given that you have 3.00 L of a 0.340 M solution of aluminum nitrate, first calculate the number of mol in aluminum nitrate = M*V = (.340)(3.00) = 1.02 moles of aluminum nitrate. Step 2 Determine the number of ions of your molecule of interest that are present in the substance. With the aluminum nitrate
