A mixture of carbon dioxide and oxygen has volume 
, temperature 300 K , pressure 100 kPa and mass 13.2 g . The number of moles of carbon dioxide and oxygen gases in the mixture respectively are 
.(Assume both carbon dioxide and oxygen gases behave like ideal gases) [ 
]
Text Solution
Verified by ExpertsC
First, we determine the total number of moles ( 
) in the mixture using the Ideal Gas Law: PV = nRT. Given the values:
• Pressure (P): 
• Volume (V): 
• Temperature (T): 300 K
• Gas Constant (R): 
1. Mole equation: 
2. Mass equation: 
(where 44 and 32 are the molar masses of 
and 
respectively)
3. Solve for individual moles
Using the first equation to express 
as 
, we substitute this into the mass equation:
Then, calculate
