Molarity
01
the concentration of a solute in a solution, measured in moles per liter (mol/L or M)
Example
A solution with a molarity of 0.5 M means there are 0.5 moles of solute in each liter of the solution.
The molarity of a calcium chloride solution may be expressed as 1.5 M, meaning 1.5 moles of CaCl₂ per liter of the solution.
The molarity of a hydrochloric acid solution may be expressed as 2 M, indicating 2 moles of HCl per liter.
If a solution has a molarity of 4 M, it means there are 4 moles of the solute in each liter of the solution.
Hydrogen peroxide with a molarity of 6 M means there are 6 moles of H₂O₂ per liter.
