In a quality-control test, a sample of a 0.20 mol dm−30.20\,\mathrm{mol\,dm^{-3}}0.20moldm−3 solution of reactant T reacts completely. The test collects 0.384 dm3 of gas at RTP. Each mole of T forms one mole of gas. One mole of gas occupies 24 dm3 at RTP.
What volume of the solution of T was in the sample?
