A
vapor pressure
5
Q
How can you tell if a solution is nonvolatile?
A
Dr. Ross doesn’t provide us with a vapor pressure
6
Q
How do you calculate molality?
A
m=moles solute/kg solvent
7
Q
What are the steps for calculating molar mass?
A
- use FP to find molality
- use molality to find moles solute
- molar mass = g/moles
