Final answer:
To find the surface pressure on Venus in atm, we need to calculate the partial pressure of nitrogen (N2) in atm. The surface pressure on Venus is approximately 0.0785 atm.
Step-by-step explanation:
To find the surface pressure on Venus in atm, we need to calculate the partial pressure of nitrogen (N2) in atm. First, we convert the nitrogen percentage to a decimal: 3.0% = 0.03. Next, we use Dalton's Law of Partial Pressures, which states that the total pressure is equal to the sum of the partial pressures of each gas.
Thus, the partial pressure of nitrogen (PN2) is calculated as:
PN2 = Percentage of N2 x Total Pressure = 0.03 x 2050 torr
Finally, we convert the partial pressure of nitrogen to atm by dividing by 760 torr (1 atm = 760 torr).
Surface Pressure on Venus = PN2 / 760 torr
So, the surface pressure on Venus is approximately 0.0785 atm.
