WHAT YOU’LL LEARN TO DO: Review the ideal gas law; use the ideal gas law to calculate the mol of an unknown volatile liquid in a gas phase (the grams and mols of the sample will be used to calculate molar mass).
Learning Objectives
By the end of this section, you will be able to:
- Calculate molar mass using the ideal gas law and laboratory data.
- Determine the identity of an unknown from a list of choices.
- Determine how sources of error affect your measurements.
