General Objectives:

1. Demonstrate an understanding of the moles as the unit for comparison of amounts of matter

Specific Objectives: Students will be able to

1.Define the term mole

2. Determine the molar of given compounds

3. Complete calculations with mole and mass and number of particles in elements and compounds.

Lesson connections to previously learned material:

Students will use their knowledge of mass number to do calculations with mole

IntroductionTeaching strategies/ActivityMaterials/Text References

Put items in groups with 12, 2 or 3 items in a group in front of the students and ask them to give a collective name for the number of items in the groups. Next put a handful of salt grains in front of the students and ask them to give a collective name for the number of grains. Use this to introduce avogadros number. Guided discovery

Class discussionChemistry for CSEC textbookCounters, salt

New Material

The mole is a name given to 6.0 x 1023 number of items. Like a dozen is 12 etc. The mole was derived in comparison to the exact number of atoms in 12g of carbon-12 because it is hard to determine the mass of exactly one atom.

New Material

The relative atomic of elements is equal to

6.0 x 1023 atoms of given elements which is equal to 1 mole. The mass of one mole of a compound is the total relative atomic mass of each element in the compound Eg. Molar mass of NaCl.

M(NaCl) = 23 + 35.5 = 58.5gmol-1 (this is the unit for molar mass)LectureClass DiscussionGroup Activity

New Material

The number of particles (atoms/molecules) in an element compound is directly related to the mass and the number of moles. E.g.

1 mole of Ca = 6.0 x 1023 atoms

Therefore 2 mole of Ca = 2 x 6.0 x 1023 = 12 x 1023 atoms. 1 mole Ca = 40 g = 6.0 x 1023 atoms

Therefore 40g of Ca = 6.0 x 1023 atoms.

Lesson Recap : Students will determine the molar mass of given compounds and calculate the number of particles in given elements and compounds.

Homework given: Students will complete work given and calculate the number of moles of specific mass of elements and compounds. Students will also calculate the number of specific particles in given compounds.
