• Molarity is temperature dependent (moles unaffected, but volume is affected). • Dilution calculations are much easier in terms of molarity! Therefore: a)Use equation 16’ to calculate the stock solution M based on the stock solution m. b)Use Use M i V i = M f V f to determine the of M of the each dilution.

Molarity and Solutions intro D uction Molarity is a measure of the concentration of solute in a solution, where the solute is measured in moles. Moles are the molecular weight of a substance expressed in grams. Molarity equals moles (mol) per liter (l). 1 molar = 1 mol/l = 1 M. prefixes can be added to molarity (M) as with the standard metric ...
