Molarity

How is Molarity calculated?

• Molarity = grams of solute / liters of solution.

• Molarity = moles of solute / liters of solution.

• Molarity = moles of solution / liters of solute.

• Molarity = liters of solute / grams of solution.

How does temperature affect Molarity?

• Molarity remains constant regardless of temperature changes.

• Molarity can change with temperature due to changes in volume.

• Temperature has no effect on the concentration of solutions.

• Molarity increases with temperature due to increased solute solubility.
