the apparent molar mass of the mixture, we need to calculate the total mass of the mixture and the total number of moles of each component.Given:- Mass of oxygen = 2 kg- Mass of nitrogen = 3 kgFirst, let's calculate the number of moles of each component using their respective molar masses:- Molar mass of oxygen (O₂) = 32 g/mol- Molar mass ofN₂) = 28 g/molNumber of moles of oxygen:
Number of moles of nitrogen:
Next, we calculate the total mass of the mixture:
Now, we calculate the total number of moles in the mixture:
Finally, we calculate the apparent molar mass of the mixture:
Therefore, the correct answer is:
