Answer: The partial pressure of the water vapor is 1.108 atm

Explanation:

According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

$p_{total}=p_A+p_B$

Thus $p_{total}=p_{N_2}+p_{H_2O}$

Given: $p_{total}$ =4.015 atm

$p_{N_2}$ = 2.907 atm

$p_{H_2O}$ = ?

Thus $4.015=2.907+p_{H_2O}$

$p_{H_2O}=1.108atm$

Thus the partial pressure of the water vapor is 1.108 atm
