How to calculate concentration, volume, moles
N=cv/1000 (cm3)
N=cv (dm3)
Standard solution
Solution of known concentration
Prepared by dissolve=Ingrid exact mass of solute in solvent, making up solution to exact volume
Concentration
Amount of solute in moles dissolved in 1dm3
Other ways of showing concentration
Mass concentrations=g dm3
How to convert between g dm-3 and mol dm-3
G Dm-3 divide by RFM
Mol dm-3 multiply by RFM
Molar volume
Volume per mole of gas molecules at stated temperature and pressure
Volume equation at room temperature and 1 atm
Volume=n x 24000 (cm-3)
Volume=n x 24 (dm-3)
Ideal gas equation assumptions
Random motion of molecules
Negligible size
Elastic collisions
No IMF
Ideal gas equation
PV=nRT
Units of ideal gas equation
