1- we find Effective molecular mass of mixers=2×V.D.
2-let 100 me se x gram NO2 hai tab mole fraction
mole fraction =X/46/
X/46 + (100-x)/92
3-EMM= molefraction of No2 × molecular weight of
NO2
+ molefraction of N2O4× molecular weight of N2O4
you find X(gram) ... and find no. of mole

The vapor density of a mixture containing NO2 and N2O4 is 38.3 at 26.7...
Given:
- Vapor density of the mixture = 38.3
- Temperature = 26.70°C
To Find:
- Number of moles of NO2 in 100g of the mixture
Explanation:
1. Understanding Vapor Density:
Vapor density is the ratio of the density of a gas to the density of hydrogen gas at the same temperature and pressure. It is commonly used to determine the molecular formula of a gas.
2. Calculation of Vapor Density:
The vapor density can be calculated using the following formula:
Vapor Density = (Molar Mass of the Gas) / (Molar Mass of Hydrogen Gas)
3. Calculation of Molar Mass:
The molar mass of a substance can be calculated by summing up the atomic masses of all the atoms present in that substance.
4. Calculation of Molar Mass of NO2:
- Nitrogen (N) atomic mass = 14.01 g/mol
- Oxygen (O) atomic mass = 16.00 g/mol
Molar mass of NO2 = (14.01 g/mol) + (2 * 16.00 g/mol) = 46.01 g/mol
5. Calculation of Molar Mass of N2O4:
Molar mass of N2O4 = (2 * 14.01 g/mol) + (4 * 16.00 g/mol) = 92.02 g/mol
6. Calculation of Molar Mass of Mixture:
Let the number of moles of NO2 be x and the number of moles of N2O4 be y.
The molar mass of the mixture can be calculated using the following equation:
Molar Mass of Mixture = (x * Molar Mass of NO2) + (y * Molar Mass of N2O4)
7. Calculation of Ratio of Moles:
The ratio of moles of NO2 to N2O4 can be calculated using the formula:
Ratio of Moles = (x / y)
8. Calculation of Vapor Density:
The vapor density of the mixture can be calculated using the formula:
Vapor Density = (Molar Mass of Mixture) / (2 * Molar Mass of Hydrogen Gas)
9. Calculation of Moles of NO2:
The number of moles of NO2 in 100g of the mixture can be calculated using the formula:
Moles of NO2 = (Mass of NO2) / (Molar Mass of NO2)
10. Solving the Equations:
By substituting the given values and using the above equations, we can solve for the number of moles of NO2.
Final Answer:
The number of moles of NO2 in 100g of the mixture is between 0.430 and 0.440 moles.
- Vapor density of the mixture = 38.3
- Temperature = 26.70°C

5. Calculation of Molar Mass of N2O4:
Molar mass of N2O4 = (2 * 14.01 g/mol) + (4 * 16.00 g/mol) = 92.02 g/mol
6. Calculation of Molar Mass of Mixture:
Let the number of moles of NO2 be x and the number of moles of N2O4 be y.
The molar mass of the mixture can be calculated using the following equation:
Molar Mass of Mixture = (x * Molar Mass of NO2) + (y * Molar Mass of N2O4)
7. Calculation of Ratio of Moles:
The ratio of moles of NO2 to N2O4 can be calculated using the formula:
Ratio of Moles = (x / y)
8. Calculation of Vapor Density:
The vapor density of the mixture can be calculated using the formula:
Vapor Density = (Molar Mass of Mixture) / (2 * Molar Mass of Hydrogen Gas)
9. Calculation of Moles of NO2:
The number of moles of NO2 in 100g of the mixture can be calculated using the formula:
Moles of NO2 = (Mass of NO2) / (Molar Mass of NO2)
10. Solving the Equations:
By substituting the given values and using the above equations, we can solve for the number of moles of NO2.
Final Answer:
The number of moles of NO2 in 100g of the mixture is between 0.430 and 0.440 moles.
