The number of moles of air present is 0.056 mole
What is the ideal gas equation?
The ideal gas is one in which molecules do not attract or repel each other.Many gases like oxygen,nitrogen, carbon di oxide can be treated as the ideal gases as particular temperature and pressure.The real gases at high temperature and lower pressure can be treated as ideal gases.
The given data in the question is
Volume = 1.35 L
Pressure (P) = 750 torr
Temperature (T) = 17 °C = 17 + 273 = 290 K
Gas constant (R) = 62.396 L•torr/mol•K
The number of moles (n) =?
How to determine the number of moles:
The number of moles present can be obtained by using the ideal gas equation as illustrated below:
[tex]PV=nRT[/tex]
Divide both sides by RT
[tex]n=\dfrac{PV}{RT}[/tex]
[tex]n=\dfrac{(750\times 1.350}{62.396\times 290)}[/tex]
[tex]n=0.056\ moles[/tex]
Hence, the number of moles of air present is 0.056 mole
