1. Analytical Techniques Studied

2. The Mole The mole is the basis of all our calculations.
When in doubt, calculate the number of moles present
Taken from Nelson Chemistry pg 4

3. Unit Conversions - Temperature
When converting from Celsius to Kelvin add 273 degrees When converting from Kelvin to Celsius subtract 273 degrees
Taken from Nelson Chemistry pg 5

4. Unit Conversions – Mass & Volume
Taken from Nelson Chemistry pg 5

5. Unit Conversions – Pressure
When converting pressure, convert to atmospheres before converting to mm of mercury or pascals/kilopascals
Taken from Nelson Chemistry pg 5

6. Key Formulae PV = nRT C1V1 = C2V2 V = n × Vm n = C × V
P = Pressure (kilopascals)
V = Volume (L)
n = moles
R = 8.31 J mol-1 K-1
T = Temperature (°K)
C = Concentration (M)
m = mass (g)
Mr = molar mass
Vm = molar volume
n = C × V
Molar volume:
22.4L at STP
24.5L at SLC
