Answer: The partial pressure of nitrogen on Venus is 81 mmHg

Step-by-step explanation:

To calculate the partial pressure of the gas, we use the equation given by Raoult's law, which is:


p_(A)=p_T* \chi_(A)

where,


p_A = partial pressure of nitrogen gas = ?


p_T = total pressure = 2700 mmHg


\chi_A = mole fraction of nitrogen gas = 3.0 % = 0.03

Putting values in above equation, we get:


p_(N_2)=2700mmHg* 0.03\\\\p_(N_2)=81mmHg

Hence, the partial pressure of nitrogen on Venus is 81 mmHg
