Molarity

Molarity is a concentration unit that can be measured by the number of moles of solute per liter of solution. 

The molarity formula is: 

                               moles of solute (mol)

                               ___________________

                                

                               volume of solution (L)

it can also be written as:

 

                             M= N/V

where N is the number of Moles and V is the volume

the unit symbol for mol/L is "M", which can be written as "molar". 

Here are some examples:

If 3.0 L of solution contained 6.0 Mol of FeCI, what is the molarity of the FeCI?

molar concentration =  6.0 mol

                                ________  = 2.0 M

                                   

                                  3.0 L

 

                          Therefore, the molarity of the FeCI is 2.0 M.
