    Pv=nrt
In summary, the value of V on Venus at STP can be calculated using the ideal gas law, PV=nRT, which depends on the values of pressure, number of moles, and temperature on Venus. To solve for V, the ideal gas law can be rearranged to isolate V. The unit for V on Venus at STP will vary depending on the units used for pressure, number of moles, temperature, and the gas constant. Compared to Earth, the value of V on Venus at STP will be smaller due to the higher pressure and temperature on Venus. While the ideal gas law can be applied to Venus at STP, it may not be accurate due to the extreme conditions on the planet.

Homework Statement



The conditions of standard temperature and pressure STP are a temperature of 0.00 C and a pressure of 1.00 atm.

For a scientist on Venus, an absolute pressure of 1 Venusian-atmosphere is 92 Earth-atmospheres. Of course she would use the Venusian-atmosphere to define STP. Assuming she kept the same temperature, how many liters would 1 mole of ideal gas occupy on Venus?



The Attempt at a Solution



PV=nRT
(1/92 atm)V=1 mol(.08205746 (L atm)/(K mol))(273.15 C)
V=2062.086

but that isn't right

The pressure at the surface of Venus is 92 atmospheres, not 1/92nd of an atmosphere.

because it doesn't take into account the different temperature and pressure on Venus.

To solve PV=nRT for V on Venus at STP, we need to consider the different temperature and pressure conditions on Venus compared to Earth. The temperature on Venus is much higher than 0.00 C, so we need to use the corresponding temperature in Kelvin. Additionally, the pressure on Venus is not 1.00 atm, but rather 92 times that of Earth's atmosphere. Therefore, the correct equation to use is:

(1/92 atm)V = 1 mol (0.08205746 (L atm)/(K mol))(737.15 K)

Solving for V, we get:

V = 15.81 liters

So, 1 mole of an ideal gas on Venus at STP would occupy 15.81 liters, which is significantly larger than the volume on Earth due to the higher temperature and pressure. It is important to consider the specific conditions of a planet when solving equations like PV=nRT.
 

1. What is the value of V on Venus at STP?

The value of V on Venus at STP can be calculated using the ideal gas law, PV=nRT. It will depend on the values of pressure (P), number of moles (n), and temperature (T) on Venus at STP.

2. How do you solve for V on Venus at STP?

To solve for V on Venus at STP, you can rearrange the ideal gas law to isolate V. The equation will be V=nRT/P. Plug in the values for n, R, P, and T to get the numerical value for V.

3. What is the unit for V on Venus at STP?

The unit for V on Venus at STP will depend on the units used for pressure, number of moles, temperature, and the gas constant. Typically, the unit for V will be in liters (L) or cubic meters (m^3).

4. How does the value of V on Venus at STP compare to Earth's value?

The value of V on Venus at STP will be different from Earth's value due to the differences in pressure, number of moles, and temperature on the two planets. Venus has a much higher atmospheric pressure and temperature compared to Earth, which will result in a smaller value of V.

5. Can the ideal gas law be applied to Venus at STP?

Yes, the ideal gas law can be applied to Venus at STP as long as the gas behaves ideally. This means that the gas particles are not interacting with each other and there are no phase changes occurring. However, the ideal gas law may not be accurate for gases on Venus due to the extreme conditions on the planet.
