  1. Mythic prefixes:

~1 m = 1000 mm

  1. Compound units:

~ 10 g / ml → 1 ml = 10 g

  1. Periodic table for masses
  2. Balanced chemical equations

        ~1 mol = 6.02 x 1023 = Avogadro’s number (atoms)

Balancing chemical equations

Example: 2H2 + O2 → 2H2O

2 mol H2 = 1 mol O2

2 mol H2 = 2 mol H2O

2 mol O2 = 2 mol H2O

Example: How many moles O2 needed for 7.0 mol of H2O?

        7.0 mol H2 x → 7.0 mol H2O needed

Example: How many moles of H2O when you have 2.1 mol H2?

        2.1 mol H2 x → 2.1 mol H2O

Example: How many moles H2O formed with 100g of O? ( 2H2ro2 → 2H2O)

        100g O2 → ? H2O

        100 g O2

0 = 16 g x 2 = 32g O2 = 1 mol O2

1 mol O2 = 2mol H2O

**grams to moles**

100 g O2 x x = 6.25 mol H2O

Example: How many g H2 needed for 100g H2O?

2H2rO2 = 2H2O

~2 mol H2 = 2 mol H2O

~ H2 = 1 x 2 = 2g

2.0 g H2 = 1 mol H2

~H2O

H: 1 x 2 = 2

O: 16 = 16

H2O = 18 g H2O = 1 mol H2O

100g H2O x xx→ 11.0 g H2
