Question

A mixture of xenon and argon gases, in a 5.91 L flask at 13 °C, contains 43.3 grams of xenon and 3.83 grams of argon. The partial pressure of argon in the flask is atm and the total pressure in the flask is atm.

Expert Solution

Step 1: Given information :

Given :

43.3 grams of xenon

3.83 grams of argon

Volume = 5.91 L

Temperature is at 13 °C = 286.15K

To find the partial pressure of argon and the total pressure in the flask, we can use the ideal gas law:

$P V = n RT$

Where:

$Error converting from MathML to accessible text.$ is the pressure,
$Error converting from MathML to accessible text.$ is the volume,
$Error converting from MathML to accessible text.$ is the number of moles,
$Error converting from MathML to accessible text.$ is the ideal gas constant,
$Error converting from MathML to accessible text.$ is the temperature in Kelvin.

First, let's find the moles of each gas using their given masses and the molar masses of xenon ( $Error converting from MathML to accessible text.$ ) and argon ( $Error converting from MathML to accessible text.$ ).
