Moles and Volumes
1cm3 = 1ml
1dm3 = 1000cm3 = 1000ml = 1l
Concentration is the amount of solute (moles) dissolved in each 1dm3 of solution
N = c x V
n = moles
c = concentration
V = volume (dm3)
A standard solution is a solution of known concentration
Creating a standard solution
Solvent is the liquid the solid is dissolved in
Solution is the combination of liquid and solid
Molar gas volume is the volume per mole of gas molecules at a stated
RTP is 20oC and 1 atmosphere
4 assumptions for the ideal gas equations
p = pressure (Pa)
V = volume (m3)
n = Moles
R = Ideal Gas Constant (8.314Jmol-1k-1)
T = Temperature (K)

A standard solution is a solution of known concentration
Creating a standard solution
- Dissolve an exact mass of solute
- Make up solution to exact volume
