Tro's Introductory Chemistry, Chapter 13 48 Preparing a 1.00 M NaCl Solution Weigh out 1 mole (58.45 g) of NaCl and add it to a 1.00 L volumetric flask. Step 1 Step 2 Add water to dissolve the NaCl, then add water to the mark. Step 3 Swirl to Mix
Example 13.3: Calculating Molarity
Tro's Introductory Chemistry, Chapter 13 50 Example: Calculate the molarity of a solution made by putting 15.5 g of NaCl into a beaker and adding water to make 1.50 L of NaCl solution.
Tro's Introductory Chemistry, Chapter 13 51 Example: Calculate the molarity of a solution made by putting 15.5 g of NaCl into a beaker and adding water to make 1.50 L of NaCl solution. Write down the given quantity and its units. Given: 15.5 g NaCl 1.50 L solution
Tro's Introductory Chemistry, Chapter 13 52 Write down the quantity to find and/or its units. Find: molarity (M) Information Given: 15.5 g NaCl; 1.50 L sol’n Example: Calculate the molarity of a solution made by putting 15.5 g of NaCl into a beaker and adding water to make 1.50 L of NaCl solution.
Tro's Introductory Chemistry, Chapter 13 53 Collect Needed Equations and Conversion Factors: Molar Mass NaCl = 58.44 g/mol 58.44 g NaCl = 1 mol Information Given: 15.5 g NaCl; 1.50 L sol’n Find: molarity, M Example: Calculate the molarity of a solution made by putting 15.5 g of NaCl into a beaker and adding water to make 1.50 L of NaCl solution. solution liters solute moles Molarity =
54 Design a Solution Map: Volume Solution Mass Solute Molarity Information Given: 15.5 g NaCl; 1.50 L sol’n Find: molarity, M CF: 58.44 g = 1 mol NaCl; Example: Calculate the molarity of a solution made by putting 15.5 g of NaCl into a beaker and adding water to make 1.50 L of NaCl solution. solution liters solute moles Molarity = L Solution Mole Solute liters moles M = NaCl g 58.44 moles 1 already liters
Tro's Introductory Chemistry, Chapter 13 55 NaCl mol 2 5 0.26 g 58.44 NaCl mol 1 NaCl g 15.5 = × Apply the Solution Map Information Given: 15.5 g NaCl; 1.50 L sol’n Find: molarity, M CF: 58.44 g = 1 mol NaCl; Example: Calculate the molarity of a solution made by putting 15.5 g of NaCl into a beaker and adding water to make 1.50 L of NaCl solution. solution liters solute moles Molarity = solution L 1.50 NaCl mol 2 5 26 . 0 solution liters solute moles Molarity = = = 0.177 M NaCl
56 Check the Solution The units of the answer, M, are correct. The magnitude of the answer makes sense since the mass of solute is less than the 1 mole and the volume is more than 1 L. molarity of solution = 0.177 M Information Given: 15.5 g NaCl; 1.50 L sol’n Find: molarity, M CF: 58.44 g = 1 mol NaCl; Example: Calculate the molarity of a solution made by putting 15.5 g of NaCl into a beaker and adding water to make 1.50 L of NaCl solution. solution liters solute moles Molarity =
Example 13.4: Using Molarity in Calculations
Tro's Introductory Chemistry, Chapter 13 58 Example: How many liters of a 0.114 M NaOH solution contains 1.24 mol of NaOH?
Tro's Introductory Chemistry, Chapter 13 59 Example: How many liters of a 0.114 M NaOH solution contains 1.24 mol of NaOH?

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
