1. 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

2. 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.
