Answer:
Mole fraction SF₄: 0,121
Mole fraction CO₂: 0,879
Partial pressure SF₄: 0,134 atm
Partial pressure CO₂: 0,968 atm
Total pressure: 1,102 atm
Explanation:
The moles of sulfur tetrafluoride gas and carbon dioxide gas are:
5,29g SF₄×= <em>0,0489 moles SF₄</em>
15,6 CO₂×= <em>0,354 moles CO₂</em>
Mole fraction SF₄:
= <em>0,121</em>
Mole fraction CO₂:
= <em>0,879</em>
It is possible to obtain partial pressure of both gases with moles of each gas using:
P = nRT/V
Where n are respective moles, R is gas constant (<em>0,082atmL/molK</em>), T is teemperature (27°C=<em>300,15K</em>), V is volume (<em>9,0000L)</em>
Replacing:
Partial pressure SF₄: <em>0,134atm</em>
Partial pressure CO₂: <em>0,968atm</em>
Now, the sum of the partial pressures is the total pressure in the tank, that means:
Total pressure: 0,134atm + 0,968atm = <em>1,102atm</em>
