Although the planet Venus is similar in size and composition to the Earth, the atmosphere is not conductive to life. The average temperature is about 740 K, the atmospheric pressure is about 91 atm, and the atmosphere is mostly carbon dioxide.
Calculate the moles of atmospheric gas in 1.0 L at the surface of Venus. Calculate the mass of atmospheric gas (assume it all to be carbon dioxide) in 1.0 L. Calculate the density of Venus's atmosphere at its surface in units of g/L, g/mL, and kg/kL.
