PP022 - Finding the relative molecular mass of a volatile liquid
Click to download Document.
The relative molecular mass of a volatile liquid can be found by measuring the volume occupied by a known mass of the liquid's vapour at room temperature and pressure. This method avoids the use of ga.. more
