P = 91.7atm
T = 741 K
Lets derive the equation to be used
use:
p*V=n*R*T
p*V=(mass/molar mass)*R*T
p*molar mass=(mass/V)*R*T
p*molar mass=density*R*T
Put Values:
91.7 atm *43.36 g/mol = density * 0.08206 atm.L/mol.K *741.0
K
density = 65.4 g/L
Answer: 65.4 g/L

2. Atmospheric Mass Venus and Earth have about the same mass and radius, but the atmospheric pressure on the surface of Venus is measured to be 90 times larger than the pressure at the surface of the Earth. (a) Assuming Venus' atmosphere is pure CO2 and Earth's atmosphere is pure N2, estimate the atmospheric scale height for each planet. For simplicity you can assume that both atmospheres are isothermal with T = 550 K for Venus and T = 250...

Enter your answer in the provided box. Although the planet Venus is similar in size and composition to Earth, the carbon dioxide atmosphere at its surface is not conducive to life. The average temperature is about 740 K, and the atmospheric pressure is extremely high. If the atmospheric pressure is 95 atm, calculate the mass of atmospheric gas (assume it all to be carbon dioxide) in 2.7 L.

At the surface of Venus the average temperature is a balmy 460 ∘C due to the greenhouse effect (global warming!), the pressure is 92 Earth-atmospheres, and the acceleration due to gravity is 0.894 gEarth. The atmosphere is nearly all CO2 (molar mass 44.0g/mol) and the temperature remains remarkably constant. We shall assume that the temperature does not change at all with altitude. Part A What is the atmospheric pressure 2.00 km above the surface of Venus? Express your answer in...

The system is warmed to a temperature of 375 K, with the stopcock open to the atmosphere. The stopcock is then closed, and the flask cooled to its original temperature. A) What is the final pressure of the ethane in the flask? B) Find...

P2) (50 pts.) The boiling temperature of nitrogen at atmospheric pressure at sea level (1 atm pressure) is -196°C. Therefore, nitrogen is commonly used in low-temperature scientific studies, since the temperature of liquid nitrogen in a tank open to the atmosphere will remain constant at -196°C until it is depleted. Any heat transfer to the tank will result in the evaporation of some liquid nitrogen, which has a heat of vaporization of 198 kJ/kg and a density of 810 kg/m3...
