Solution Dilution Quiz

What happens to the concentration of a solution when more solvent is added?

• It remains the same.

• It becomes less concentrated.

• It becomes more concentrated.

• It evaporates.

In the equation M1V1 = M2V2, what does 'M' represent?

• Moles

• Milliliters

• Molarity

• Mass

What does 'V' stand for in the dilution equation?

• Velocity

• Volume

• Viscosity

• Voltage

Which components of the dilution equation apply to the concentrated solution?

• M1 and V1

• M2 and V2

• Only V2

• Only M1

Why is the amount of moles conserved during dilution?

• Because the solute is not altered.

• Because the solvent is changed.

• Because the solvent is not altered.

• Because the solute is changed.

In the example problem, what is the molarity of the concentrated HCl solution?

• 3 molar

• 12 molar

• 5 molar

• 10 molar

What is the volume of the diluted HCl solution in the example problem?

• 20 milliliters

• 15 milliliters

• 10 milliliters

• 5 milliliters

How do you isolate V2 in the equation M1V1 = M2V2?

• Subtract M1 from both sides

• Divide both sides by M2

• Divide both sides by M1

• Multiply both sides by M2

What is the final calculated volume of the concentrated solution in the example?

• 3 milliliters

• 10 milliliters

• 12 milliliters

• 5/2 milliliters

Why might you avoid expressing the final answer as a fraction?

• To make it easier to read

• To avoid confusion with significant figures

• To simplify the equation

• To match the units
