Calculating Molarity (Silent Movie Style)

What is the correct formula for calculating molarity?

• Molarity = liters / moles

• Molarity = moles / liters

• Molarity = grams / liters

• Molarity = moles * liters

What are the standard units for expressing molarity?

• grams per liter (g/L)

• moles per milliliter (mol/mL)

• moles per liter (mol/L)

• liters per mole (L/mol)

A solution is prepared by dissolving 3.0 moles of a solute in enough solvent to make a total volume of 1.2 liters. What is the molarity of this solution?

• 0.4 M

• 2.5 M

• 3.6 M

• 1.8 M

Which expression correctly represents the calculation for molarity if 3.0 moles of a substance are dissolved to create a 1.2-liter solution?

• 1.2 L / 3.0 mol

• 3.0 mol * 1.2 L

• 3.0 mol / 1.2 L

• 3.0 L / 1.2 mol
