kidia Posted February 27, 2006 Share Posted February 27, 2006 I want to calculate the density of plutonium,which has molar mass of 244 and atomic number 94.my problem is the volume can I use the standard volume of gas molecule 22.4? Link to comment Share on other sites More sharing options...
timo Posted February 28, 2006 Share Posted February 28, 2006 Assuming you mean "does 1 mol Pu take up roughly 22.4 l of volume?" then the answer is no. The 22.4 l/mol are an approximation for little-interacting gases at standard pressure and standard temperature. Just try it out for water. Hopefully, you´ll quickly see that a water density of ~2 g/l is not a realistic value. Link to comment Share on other sites More sharing options...
insane_alien Posted February 28, 2006 Share Posted February 28, 2006 if you want the value of it when its in a gaseuos state then yeah go ahead but remember that the temp has to be above the boiling point. Link to comment Share on other sites More sharing options...
