Unit 11 Exit Ticket #2: Molarity

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 the number of grams of solute in a solution?

Back

To calculate grams of solute, use the formula: grams = moles × molar mass.

Front

What is the formula for calculating molarity?

Back

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