Dilution and Concentration Calculations

What is the process called when a more concentrated solution is used to make a desired more dilute solution?

• Evaporation

• Filtration

• Dilution

• Distillation

How many moles of glucose are needed to make 0.50 L of a 0.25 M glucose solution?

• 0.125 moles

• 0.25 moles

• 0.50 moles

• 1.0 moles

What volume of 1.0 M glucose solution is needed to obtain 0.125 moles of glucose?

• 0.125 L

• 0.25 L

• 0.50 L

• 1.0 L

What is the final volume of the dilute solution after adding water to the concentrated solution?

• 0.25 L

• 0.50 L

• 1.0 L

• 2.0 L

Write this equation down on your dilutions note page. M1V1=M2V2

• Okay, I wrote it down.

• Already written down.

Match the following to the correct description.

• Final concentration in molarity (M)

• M1

• Initial volume in liters (L)

• V1

• Dilution equation

• M2

• Initial concentration in molarity (M)

• V2

• Final volume in liters (L)

• M1V1=M2V2

You have 25 L of a 3 M solution. How much water should you add to create a 1 M solution?

• The equation I should use.

• M2

• 1

• V2

• What I'm solving for with my equation.

• M1

• 25

• M1V1=M2V2

• 3M

• V1

You have 25 L of a 3 M solution. How much water should you add to create a 1 M solution?

Choose the correct setup.

• (25L)(3M)=(V2)(1M)

• (25L)(1M)=(V2)(3M)

• (25L)(3M)=(1M)

• (25L)/(3M)=(V2)/(1M)

You have 25 L of a 3 M solution. How much water should you add to create a 1 M solution?
