  1. Do Now • Write the formula for Sodium Chlorate • Write the name for SnO • Write a reaction for the decomposition of Aluminum Oxide • How many molecules of oxygen are formed after the decomposition of 58g of aluminum oxide?

  2. HW Q and A

  3. Vocabulary • Concentration – a measurement of the amount of solute that is dissolved in a given quantity of solvent; usually expressed as mol/L

  4. Vocabulary • Molarity (M) – the concentration of solute in a solution expressed as the number of moles of solute dissolved in 1 liter of solution

  5. Example 1 • How would you make a 250mL of .5M of sodium hydroxide solution?

  6. Example 2 (Try): • How many grams of AgNO3are needed to make 800mL 1.5M AgNO3 solution?

  7. Vocabulary • Hydrate – a solid compound containing water molecules combined in a definite ratio as an integral part of the crystal

  8. Example 3 • How many grams of solid lead (II) sulfate heptahydrate are needed to make 3.4L of 0.025M solution?
