Lab freezing point depression answers
WebSep 3, 2024 · Multiply the original molality ( m) of the solution by the number of particles formed when the solution dissolves. This will give you the total concentration of particles dissolved. Compare these values. The higher total concentration will result in a higher boiling point and a lower freezing point. Example 13.9. 1. WebView 1.4.3 Lab_ Freezing Point Depression.pdf from CHEM 1013 at Oklahoma City University. Answer these questions before beginning the lab. Be sure to turn them in when you submit your lab report.
