A technician has 0.24 mol of solute Q. It is used to make a solution with a concentration of 0.30 mol dm−30.30\,\mathrm{mol\,dm^{-3}}0.30moldm−3 for a materials-testing trial.
What volume of solution can the technician make?
1.25 dm31.25\,\mathrm{dm^3}1.25dm3
0.80 dm30.80\,\mathrm{dm^3}0.80dm3
800 dm3800\,\mathrm{dm^3}800dm3
0.072 dm30.072\,\mathrm{dm^3}0.072dm3
