January 21, 2011: Mole to Mole Conversions (Angelo)

Mole to Mole Conversions:
- coefficients in balanced equations tell us the number of moles reacted or produced
- they can also be used as conversion factor:
3X + Y = 2Z
- WHAT YOU NEED over WHAT YOU HAVE


EXAMPLES:


1. If 0.20 mol of Methane are consumed in a combustion reaction, how many moles of CO2 are produced?

Create your balanced equation: CH4 + 2O2 -----> CO2 + H2O
Create your equation:  0.20 mol (CH4 ) * (1 mol (CO2) / 1 mol (CH4)) = ?
Calculate: 0.20 mol (CH4 ) * 1 mol (CO2) / (1 mol (CH4) = 0.2 mol (CH4))

2. When 2.0 mol of Copper (II) react with Iron (II) Chloride, how many moles of iron should be producted?

Create your balanced equation: Cu + FeCl2 -----> CuCl2 + Fe
Create your equation: 2.0 mol * (1 mol / 1 mol) = ?
Calculate: 2.0 mol

NOTE: When you are comfortable, you may remove what type of element, compound, etc. you are using.
