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
