What will be the pressure exerted by a mixture of 3.2 g of methane and 4.4 g of carbon dioxide contained in a 9 dm3 flask at 27∘C ?
It is known that,
For methane (CH4),
PCH4=3.216×8.314×3009×10−3[Since 9 dm3=9×10−3m327∘=300 K]=5.543×104Pa
For carbon dioxide (CO2),
Total pressure exerted by the mixture can be obtained as:
Hence, the total pressure exerted by the mixture is 8.314×104Pa.
