What are the two parts of a solution?
Solute, solvent
100
What are the 4 units of concentration?
Molarity, grams per liter, percent composition, parts per million
100

What does it mean when a solution is homogeneous?
Everything is mixed together uniformly.
200
What type of IMF has the lowest boiling point?
London Dispersion Force
200
What is the difference between a solute and a solvent?
Solute is what gets dissolved. Solvent is what does the dissolving.
