Following EBM metal vaporisation loss of vacuum leading to loss of beam quality

cal

With the density of metallic Ti 4.5 g/cm3 the above volume amounts to 3.6x10-6 g. And with a molar mass of Ti 204.37 g/mol it is 1.76x10-8 mol. Now: ONE mole of a gas takes a volume of 24 Liter at a pressure of 1 atmosphere or 101,325 Pa = 1013.25 millibar. Relative to this an amount of 1.76x10-8 mol vaporized titanium in a 1000 L (1 m3) volume will pr second contribute to the pressure with the following value

Help can some one work out how to put the contents of the below file in this Physics Principles DIsscusion area I am not getting it working in the wiki !
