1. Can someone help me with this question?
Calculate the concentration in mol/dm3 of:
2.3 moles of sodium chloride in 0.45 liters of solution
2. Not doing it for you, but look at the units: moles per dm3. 1 dm3 = 1L.

So if there's 2.3 moles in 0.45 litres, in 1 litre there is......how many moles?

So would it be 5.1mol/dm3?
