Exploring Molarity Concepts

What are the two components of a solution?

• Solute and solvent

• Mixture and compound

• Acid and base

• Liquid and gas

What unit is molarity measured in?

• Grams per liter

• Moles per liter

• Liters per mole

• Kilograms per liter

What does a 6 M solution of HCl indicate?

• 6 molecules of HCl per liter of solution

• 6 moles of HCl per liter of solution

• 6 liters of HCl per mole of solution

• 6 grams of HCl per liter of solution

How do you calculate the molarity of a solution?

• Divide the mass of the solute by the volume of the solution

• Multiply the moles of solute by the volume of the solution

• Multiply the mass of the solute by the volume of the solution

• Divide the moles of solute by the volume of the solution in liters

How can molarity be used as a conversion factor?

• To determine the moles or mass of solute in a given volume of solution

• To find the volume of solute in a solution

• To measure the pH of the solution

• To calculate the volume of solvent needed

What is required to prepare a molar solution from a solid compound?

• The boiling point of the solvent

• The freezing point of the solute

• The molar mass of the solute and desired volume and molarity

• The density of the solution

How is the molar mass of a solute used in calculations involving molarity?

• To calculate the pH of the solution

• To determine the volume of the solution

• To find the mass of solute needed for a specific molarity

• To measure the conductivity of the solution

What is the purpose of making dilutions?

• To create a solution with a lower concentration from a stock solution

• To increase the concentration of the solution

• To measure the exact volume of the solvent

• To decrease the pH of the solution

What does the dilution formula M1V1 = M2V2 help to calculate?

• The pH of the final solution

• The mass of the solute required

• The molarity of the solvent

• The volume of the stock solution needed

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

• It increases

• It becomes zero

• It remains the same

• It decreases
