1. Complete the 4 practice Concentration Calculations
Complete the 4 practice Concentration Calculations. Every student needs to do their own, put their name on it, and place it in the warm-up folder 
Warm-Up 2/6/14

2. Dilution
Thursday, 2/6/14

3. Solution Composition Dilute: “weak”, little dissolved solute present
Concentrated: “strong”, large amount of solute

4. Dilution
Dilution: reducing the concentration of a chemical or solution.
Usually done by increasing the ratio of solvent in the solution

5. C1V1=C2V2 C1= starting concentration (M) V1= starting volume
C2= new concentration (M)
V2= new volume

6. Example) A chemist starts with 0. 25L of a 0
Example) A chemist starts with 0.25L of a 0.40 M NaCl solution and dilutes it to 1.0L. What is the concentration of NaCl in the new solution?
