Answer:
[tex]p = \boxed{\text{593 torr}}[/tex]
Explanation:
For this question, we must use Dalton's Law of Partial Pressures:
The partial pressure of a gas in a mixture of gases equals its mole fraction times the total pressure:
[tex]p = \chi p_{\text{tot}}[/tex]
Data:
χ = 0.7808
[tex]p_{\text{tot}} = \text{ 760 torr}[/tex]
Calculation:
[tex]p = 0.7808 \times \text{ 760 torr}\\\\p= \boxed{\textbf{593 torr}}[/tex]
