What the formula for molarity?

Molarity is the number of moles of solute dissolved in one liter of solution. The units of molarity are moles per litre iemoles of solute per litre of solution. The equation for molarity is: (moles of solute)/(litres of solution) Eg 3 moles per litre or 3 mol L-1 Alternatively, volume can be measured in cubic decimeters: dm3 which are equal to litres. Eg 3 moles dm-3 is the same as 3 mol L-1 See:http://dl.clackamas.edu/ch105-04/molarity.htm
