Welcome to your "sort of" first online lab. I would like to use this first lab activity to cover some additional lecture material and then follow it up with a short activity.
Section 4.5: Concentration of Solutions
You may have noticed in lab that many of the solutions we used had a label like "3M" to indicate the concentration of the solute in the solution. 3M means 3 molar or the molarity is 3. As you will see in your text the definition of molarity (M) is the moles of solute divided by liters of solution.
Easy Example
- What is the molarity of a solution made by adding 1.23 moles of sodium chloride to 1 L of water?
- <write this out>
Answer: 1.23 M NaCl
