Molarity of Pure Substances
Molarity as well as the units that make up molarity are used indefinitely in chemistry, so fully understanding the concept is crucial. Some people do not realize that the idea of molarity extends past solutions and can be applied to pure substances (only the solvent). It is fun to get the science community thinking!
First keep in mind that there can only be a set number of mols in a given volume of space, and this number varies depending on the substance.
Assume: 1 L of water
Now how many mols of water are contained in that 1 L of water?
Recall: 1 L of water = 1000 ml water –> 1000 g water (via 1 g/ml density)
Solve for mols: (1000 g water)/(18.01 g/mol) –> 55.5 mols
Recall: we assumed 1 L water –> 55.5 mols/1 L –> 55.5 M
