Topic 5 - Concentration - part of calculations topic

What is the equation for concentration?

concentration = (moles/ volume) C =(n/v) or

concentration equals = (mass/volume) C = (m/v)

What are the units for concentration?

g/dm³ or mol/dm³

What is the equation for moles?

mole = (mass/ molar mass) n=m/Mr

What does the concentration of a solution depend on? Use copper sulphate as an example

It depends on the amount of copper sulphate that is dissolved in water to produce an aqueous copper sulphate solution.

What must you remember to convert when doing concentration calculations?

The units to dm³ for the volume

1dm³ is 1000cm³ so divide your cm unit by 1000
