Changing Boiling Point of Water Lab

Make sure calculations for #1-6 are done when you arrive to class on Thursday!



Changing the Boiling Point of Water

Purpose
To determine how adding a solute to water will affect the boiling point of water.

Calculations:
1. Calculate the molar mass of NaCl.
2. Determine the amount of salt needed in grams to make a 0 M solution of salt that has a volume of 200 mL.
3. Determine the amount of salt needed in grams to make a 0.5 M solution of salt that has a volume of 200 mL.
4. Determine the amount of salt needed in grams to make a 1.0 M solution of salt that has a volume of 200 mL.
5. Determine the amount of salt needed in grams to make a 1.5 M solution of salt that has a volume of 200 mL.
6. Determine the amount of salt needed in grams to make a 2.0 M solution of salt that has a volume of 200 mL.
