How do I work out the density of HCI at 600 celsius ?
I assume you mean the gas, hydrogen chloride.
density is mass/volume
I would use PV = nRT and rework it a little
n = g/M where M is molar mass.
PV = (g/M)RT, then
PVM = gRT and
PM = gRT/V where g/V is the density and solve for g/V = density = PM/RT. Check my algebra.
Thank you guys I will try both suggestions
OK to try both I suppose but aren't both the same? (They are the same formula!)
