1 doz = 12 1 doz eggs = 12 eggs 1 gross = gross eggs = 144 eggs 1 mol = 6.02 x mol Na atoms = 6.02 x Na atoms 1 mol NaCl = 6.02 x NaCl molecules Representative Particles: molecules - example NaCl atoms - example Ti or N or Al

·If 1 mol Al atoms = 6.02 x Al atoms, How many atoms are in 3.5 mol of Al ? A mole is just a number: 6.02 x 10 23

If you have 4.6 mol B, how many B atoms?

Molar mass = mass of one mole Molar mass of an element (one mole of its atoms) Find its mass on periodic chart. Molar mass of a compound (one mole of its molecules) Find mass of all of its individual atoms and add them up

Molar mass = mass of one mole Molar mass of an element (one mole of its atoms) Find its mass on periodic chart. Examples (give your answer without decimals, round): 1Answer? Rb #37 Bi #83 N #7 Mg #12

Molar mass = mass of one mole Molar mass of a compound (one mole of its molecules) Find mass of all of its individual atoms and add them up KMnO 4 O2 Al 2 O 3 FeO 2Answer? Examples (give your answer without decimals, round):

3The given for your problem is _______. What is the find? A mol B representative particle 3 mol FeO 4 mol Al 2 O 3 2 Ca 8 Ge

Example 1: GivenFind 2.3 g Be How many mol Be does this represent? 1 mole Be = 9.0 g Be (from mass in Periodic Chart) Solution: WHAT? 2.3 g Be 1 mol Be x = 1 9 g Be

Example 2: GivenFind 0.36 mol NaHow many grams Na does this represent? 1 mole Na = 23 g Na (from mass in Periodic Chart) Solution: WHAT? 0.36 mol Na 23 g Na 1 1 mol Na x = ans = 8.3 g Na

4Calculate the answer: Given Find 23 g Be 2.6 mol F 2 72 g SO 2
