Solutions and Molarity

What are the three types of solutions?

• saturated, unsaturated, and supersaturated

• acidic, basic, neutral

• aqueous, gaseous, solid

• diluted, concentrated, evaporated

How do you calculate the molarity of a solution?

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

• Molarity (M) = moles of solute * liters of solution

• Molarity (M) = volume of solute / liters of solution

• Molarity (M) = grams of solute / liters of solution

If you dissolve 5g of salt in 100mL of water, what is the molarity of the solution?

• 1.25 M

• 0.5 M

• 2.0 M

• 0.85 M

Explain the difference between saturated, unsaturated, and supersaturated solutions.

• Supersaturated solutions contain less solute than saturated solutions

• Saturated solutions have less solute than unsaturated solutions

• Unsaturated solutions have reached maximum solute capacity

• Saturated solutions have reached maximum solute capacity, unsaturated solutions have not, and supersaturated solutions contain more solute than normally possible.

What is the molarity of a solution containing 0.5 moles of solute in 2 liters of solvent?

• 2 M

• 1 M

• 0.25 M

• 0.5 M
