1. 7 th period - Chemistry Starter: Turn in 10.1 Notes; find the following: – The atomic mass for an atom of Calcium? – The formula mass for CaCl 2 ? – The number of moles in 12.01 grams of Carbon? – The number of moles in 65.39 grams of Zinc? – Avogadro’s number 10.1 Practice Problems in small groups (15-20 min) Educreations video (8 min) Educreations video The Mole video (5 min) The Mole video Mole Practice problems, if time allows

2. Starter Answers Using your periodic table, you should have found – The atomic mass of Calcium = 40.08 – The formula mass for CaCl 2 = 110.98 – The number of moles in 12.01 grams of Carbon = 1 mole – The number of moles in 65.39 grams of Zinc = 1 mole – Avogadro’s number = 6.02 x 10 23
