The atmosphere of Venus is mostly carbon dioxide. At the surface of Venus the temperature is 800 degrees C and the pressure is 75.0 atm
Also what will the volume of the same gas sample at STP

75 atmospheres is considerable pressure.
also due to its dipole type structure, C02 has some non-ideal
characteristics.
If you can, check out if it is a gas or liquid at that temperature and pressure. (maybe google C02,vapor pressure,pvt properties).
at STP it can be assumed ideal.
there i a compressibility factor, PV=zNRT whick may help if you can find handbook or internet data, but i would try and find out if it is a liquid or not at that temp and pressure. the pressure is hi but the temperature is too. so it may be vapor or gas or liquid.
a quick look i took says it is a supercritical fluid with properties somewhat between a gas and a liquid.
see below...good luck.
otherwise you can only assume it is an ideal gas...

You must use the equation:
PV=nRT
Solve for V,
V = (nRT)/P
STP is standard temp and pressure at sea level I believe, which is 20C and 1 atm.
Its been a while, but depending on the gas constant you use (R), you may have to convert the temperature into Kelvins.

Use the ideal gas law: PV=nRT.
