measuring mols vs grams in dilutions

Postby Summer de Vera 2C » Wed Oct 03, 2018 8:56 pm

Hi! I just wanted to clarify the reasoning for depending on the amount of mols rather than grams used for dilutions/solutions. Do we focus on the specific mols of the reactant used rather than grams because diluting/creating solutions depends on the concentration of the reactants? This is what I've understood, however I don't know if the reasoning is correct.

The unit for molarity is mol/L and so when diluting a solution the moles in the solution are relevant for finding the concentration of the new solution.

To find the mols in a molarity problem, you can multiply the concentration by the number of liters. Then you can convert to number of mols to grams.
