How do I work out the density of HCI at 600 celsius ?

Thanks

    I assume you mean the gas, hydrogen chloride.

    PV=nRT
    density is mass/volume
    n/V=P/RT
    mass/V= molmass*Pressure/RT

    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!)
