Interactive visual explanation
Adjust the moles or volume to see how concentration changes. More moles increases molarity. More volume lowers molarity.
Visual molarity
0.250 M
M = 0.50 mol ÷ 2.0 L
Understanding
Molarity measures how many moles of solute are dissolved in each liter of solution.
FAQs
What is molarity?
Molarity is the concentration of a solution measured in moles of solute per liter of solution.
What are the units of molarity?
Molarity is reported in mol/L, commonly written as M.
Can molarity be negative?
No. Moles and volume are positive quantities, so molarity cannot be negative.
