A sealed flask contains Ne, Ar, and Kr gas. If the total pressure in the flask is 3.782 atm, the partial pressure of Ne is 0.435 atm, and the partial pressure of Kr is 1.613 atm, what is the partial pressure of Ar

Respuesta :

Answer:

[tex]P_{Ar}=1.734atm[/tex] = partial pressure of Ar

Explanation:

Acccoding to dalton's law of partial pressure total pressure of system is equal to alzebraic sum of all partial pressure.

[tex]P_{total} =P_{Ne}+P_{Ar} +P_{Kr}[/tex]

[tex]P_{total}=3.782atm[/tex]

[tex]P_{Ne}=0.435 atm[/tex]

[tex]P_{Kr}=1.613atm[/tex]

[tex]P_{Ar}=P_{total}-P_{Ne}-P_{Kr}[/tex]

[tex]P_{Ar}=3.782-0.435-1.613[/tex]

[tex]P_{Ar}=1.734atm[/tex] =partial pressure of Ar
