When the solution is not alkaline, ferrate(VI) ions react with water. The reaction forms a gas with a density of 1.333 × 10–3 g cm–3, measured at room temperature and pressure, and an orange–brown precipitate.
Determine the formulae of the gas and the precipitate.
Write an equation for the reaction that takes place.

If you have the density at RTP you can find the mass present in 24 litres. This is the Mr.
