Molarity

Front

What is molarity?

Back

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

Front

What is the formula for calculating molarity?

Back

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

Front

How do you calculate the number of moles from molarity and volume?

Back

Moles = Molarity (M) × Volume (L)

Front

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

Back

Molarity relates the mass of solute (grams) to the number of moles and the volume of solution.

How do you convert mL to L for molarity calculations?

Back

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