Converting Moles to Grams/Liters/Molecules/Atoms… Do Now: Convert the following What is the conversion factor for a) feet to inches: 1 foot = ___inches b) Feet to yards: 1 foot = ___yards c) 12 ft = ______ inches d) 72 inches = ____ yards

Atomic Mass Units are too small to measure on a laboratory balance, but grams are not. Thus, we use gram formula mass (formula mass) when converting between atoms/molecules, moles and grams packet p. 8

2 3 no 1 56 56 Conversion factor 1 mol= 56 g Convert to g 2 56 1 112 g

Converting moles to grams (or grams to moles) HINT: when finding mass(grams) you have to calculate formula mass first Now w do # 3 e can and # Conversion factor is… 4 togeth er 1 mol = formula mass the set up is… Given goes here (don’t forget Unit) Nothing goes here The unit you want to convert to goes here Conversion factor goes here (this unit must be the same as the unit in your given number)

You try one on your own…p. 9 #1

• Now turn to p. 11 1 2 40 35 40 70 110 390 1 110 Conversion factor 1 mol = 110 g 3. 54 mol

You try p. 10 and 11 • Here is something that can help Grams ÷ Formula Mass Moles X

Do Now: p. 14 # 1 -2

Converting moles to liters (or liters to moles) Conversion factor is… 1 mol = 22. 4 L Turn to p. 12 the set up is… Given goes here (don’t forget Unit) Nothing goes here The unit you want to convert to goes here Conversion factor goes here (this unit must be the same as the unit in your given number)

3. 2 22. 4 71. 68 L 1 Conversion factor 1 mol = 22. 4 L

• Here is something that can help Liters ÷ 22. 4 Moles X

Converting moles to particles (or particles to moles) Hint: particles can be atoms, molecules, etc. Conversion factor is… Turn to 1 mol = 6. 02 x 1023 p. 13 the set up is… Given goes here (don’t forget Unit) Nothing goes here The unit you want to convert to goes here Conversion factor goes here (this unit must be the same as the unit in your given number)

3 6. 02 x 1023 1 18. 03 x 1023 = 1. 803 x 1024 Conversion factor 1 mol = 6. 02 x 1023 particles

You try p. 9 and 14 • Here is something that can help Liters ÷ 22. 4 Moles X X 6. 02 x 1023 ÷ Particles

Conversion Factors • 1 mole = formula mass • 1 mole = 22. 4 L • 1 mole = 6. 02 x 1023 Given goes here (don’t forget Unit)

TRICK • moles to something (grams, liters, particles) MULTIPLY • something (grams, liters, particles) to moles DIVIDE 1 mole = formula mass Grams X Moles X ÷ 6. 0 X 2 x L 4. 2 2 Liters FM 1 mole = 22. 4 L 1 mole = 6. 02 x 1023 ÷ ÷ 10 23 Particles

1 2. 5 L 1 Conversion Factors used: 1 mol = FM and 1 mol = 22. 4 L

FOR WATER • 1 g = 1 ml
