Answer:
<a href="http://socratic.org/chemistry/solutions-and-their-behavior/molarity">Molarity</a> is the concentration of a solution expressed as the number of moles of solute per litre of solution.
Explanation:
To get the molarity, you divide the moles of solute by the litres of solution
Molarity=moles of solute / litres of solution
Molarity decreases when temperature increases.
Explanation:
Molarity is affected by temperature because it is based on the volume of the solution, and the volume of a substance will be affected by changes in temperature.
In general, volume will increase when temperature increases, and vice versa. So if we use an example where temperature is increasing, that means the L in that equation is getting larger as well. Since we are dividing by L, (and dividing by a larger number gives a smaller answer,) M will become smaller.
