Molarity Flashcard

Front

What is molarity?

Back

Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution.

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.

If you have 0.5 moles of solute in 2 L of solution, what is the molarity?

Back

0.25 M

Front

What is the relationship between moles, volume, and molarity?

Back

Molarity is directly proportional to the number of moles and inversely proportional to the volume of the solution.

Front

How do you convert mL to L for molarity calculations?

Back

To convert mL to L, divide the volume in mL by 1000.
