Question 1

At room temperature and pressure, one mole of any gas occupies 24 dm3. The balanced equation for a reaction is 2N2O5→4NO2+O22\text{N}_2\text{O}_5 \rightarrow 4\text{NO}_2 + \text{O}_22N2​O5​→4NO2​+O2​. The relative formula mass of N2O5\text{N}_2\text{O}_5N2​O5​ is 108.

A sample of N2O5\text{N}_2\text{O}_5N2​O5​ with a mass of 21.6 g reacts completely. Calculate the volume, in dm3\text{dm}^3dm3, of NO2\text{NO}_2NO2​ produced at room temperature and pressure.
