Intro to Molarity

Match the following words to their definitions

• Solvent

• The substance in lesser amount in a solution. The 'thing' being dissolved

• Solute

• Less than the maximum amount of solute dissolved in a solvent

• Unsaturated

• The maximum amount of solute dissolved in a solvent

• Saturated

• The substance in greater amount in a solution. The 'thing' dissolving

• Solubility

• A measure of the maximum amount of solute dissolved in a solvent

What is the correct equation for calculating molarity?

• M = mol/L

• M = g/mol

• M = g/L

• M = L/mol
