Equivalent of 1cm3

1ml

2

Equivalent of 1dm3

1000cm3
1l

3

How to calculate concentration, volume, moles

N=cv/1000 (cm3)
N=cv (dm3)

4

Standard solution

Solution of known concentration
Prepared by dissolve=Ingrid exact mass of solute in solvent, making up solution to exact volume

5

Concentration

Amount of solute in moles dissolved in 1dm3

6

Other ways of showing concentration

Mass concentrations=g dm3

7

How to convert between g dm-3 and mol dm-3

G Dm-3 divide by RFM
Mol dm-3 multiply by RFM

8

Molar volume

Volume per mole of gas molecules at stated temperature and pressure

9

Volume equation at room temperature and 1 atm

Volume=n x 24000 (cm-3)
Volume=n x 24 (dm-3)

10

Ideal gas equation assumptions

Random motion of molecules
Negligible size
Elastic collisions
No IMF

11

Ideal gas equation

PV=nRT
