Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Use a stainless steel temperature sensor to determine the molar mass of an unknown volatile liquid at the boiling temperature of water and atmospheric pressure.
Students determine the molar mass of an unknown volatile liquid at the boiling temperature of water and at atmospheric pressure.
Students gain experience conducting the following procedures:
Beaker, 400-mL - 2
Erlenmeyer flask, 125-mL
Graduated cylinder, 100-mL
Hot plate with magnetic stirrer and stir bar
Balance - 1 per class
Clamp - 2
Unknown volatile liquid (use acetone) - 8 mL
Aluminum foil, about 4-cm by 4-cm
Paper towel, sheets - 2 or 3
Water - 600 mL
This experiment may require software and an interface for data collection.
