PV=nRT
density =mass/volume =mass/V
n=mass/M where M = molar mass
PV=mass R T /M
rearrange
PM/RT=mass/V=density
What is the density of CO2 gas at -25.2 degrees celsius and 98.0kPa?

Oh and with questions like this it is worth making sure that the question makes sense.
In this case -25.2 degrees celsius and 98.0kPa is located below and to the right of the triple point for CO2 see

and so is definitely a gas.
