Q

Concentration =

mol/dm³

A

= moles/volume
concentration: mol/dm³
Volume: dm³ - litre

2
Q

How many cm are in a dm³?

A

1000 cm³ = 1 dm³

3
Q

What are the steps for finding the concentration in moles per dm³?

A

1) Work out how many moles of the ‘know’ substance you have using this formula
2) Write down the balanced equation of the reaction and work out how many moles of the “unknown” stuff you must have had.
3) Work out the concentration of the “unknown” stuff.

4
Q

What are the steps for finding the concentration in grams per dm³?

A

1) Work out the relative formula mass for the acid.

2) Convert the concentration in moles into concentration in grams

5
Q

What is the equation for concentration? (g/dm³)

A

Work out the concentration in moles.
Then use mass = no. of moles * Mᵣ
to work out the equivalent grams per dm³
