2. Molarity
Molarity is the number of moles of
solute per liter of solution
molarity = moles of solute
liters of solution
3. Example
When people get pedicures, bath
salts are dissolved in the water.
If 40 grams of Epsom salts, MgSO4, is
dissolved in 8 liters of water, what is
the molarity?
6. Polarity
When an atom does not have even
distribution of electrons in the orbits
or shells and more end up on one
side than the other in a molecule
then, the molecule is polar
The end of one side has a positive
charge and the other has a
negative charge
7. Example
An example of a polar molecule is H20
