PLEASE HELP!CHEMISTRY QUESTION

On Venus the atmospheric pressure is 2700 mmHg and nitrogen gas makes up 3.0 % of the atmosphere. What is the partial pressure of nitrogen on Venus? mmHG

Answer 1

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
