Question 14

A technician determines the concentration of an aluminium sulfate solution. A 25.0 cm3 sample of the solution reacts exactly with 30.0 cm3 of 0.150 mol/dm3 barium nitrate solution.

The equation for the reaction is:

Al2(SO4)3+3Ba(NO3)2→3BaSO4+2Al(NO3)3\text{Al}_2(\text{SO}_4)_3 + 3\text{Ba}(\text{NO}_3)_2 \rightarrow 3\text{BaSO}_4 + 2\text{Al}(\text{NO}_3)_3Al2​(SO4​)3​+3Ba(NO3​)2​→3BaSO4​+2Al(NO3​)3​

The relative formula mass, MrM_rMr​, of aluminium sulfate is 342.

Calculate the concentration of the aluminium sulfate solution in g/dm3\text{g/dm}^3g/dm3.
