1
Q

solvent

A

the substance in which the solute dissolves

2
Q

solute

A

the substance that dissolves in the solvent

3
Q

solubility

A

ionic and dipole dipole / polar molecules are soluble

non polar molecules are slightly or not soluble in water

4
Q

mass percent

A

mass % = (mass solute / mass solution) x 100

mass % = [g solute / (g solute + g solvent)] x 100

5
Q

molarity (M)

A

M = moles solute / liters of soln

mol/l

6
Q

dilution problems

A

(m )(v ) = (m )(v )

7
Q

solution stoichiometry

A

use M and volume to find moles (mol = M*vol) and then do stoichiometry
use stoichiometry to find moles and then use M = mol/L
