Question 1196301
.
A gas mixture contains 2.5 mol N2 and 9.7 mol CO2, and has a pressure of 2.3 atm. What is the partial pressure of each gas?
~~~~~~~~~~~~~~


<pre>
Use two rules when solve such problems:


    (1)  Total pressure of a mixture of gases is the sum of partial pressures.


    (2)  Partial pressure of a gas in the mixture is proportional to its molar mass in the mixture.


It gives you, for your problem


    {{{P[N2]}}} = {{{2.3*(2.5/(2.5+9.7))}}} = 0.4713 atm  (rounded).    <U>ANSWER</U>


    {{{P[CO2]}}} = {{{2.3*(9.7/(2.5+9.7))}}} = 1.8287 atm  (rounded).    <U>ANSWER</U>
