A 0.5 dm3flask contains gas 'A' and 1 dm 3flask contains gas &...
Given data:
- Volume of flask containing gas A = 0.5 dm3
- Volume of flask containing gas B = 1 dm3
- Density of gas A = 3.0 gm dm-3
- Density of gas B = 1.5 gm dm-3
- Molar mass of A = 1/2 of B
Calculating the number of moles:
- Number of moles of gas A = Mass / Molar mass = Density * Volume / Molar mass
- Number of moles of gas B = Density * Volume / Molar mass
Given that the molar mass of A is half of B:
- Let the molar mass of gas A be x, then the molar mass of gas B = 2x
Calculating the ratio of the number of moles:
- Number of moles of A / Number of moles of B = (Density of A * Volume) / Molar mass of A / (Density of B * Volume) / Molar mass of B
- This simplifies to: Density of A / Density of B * Molar mass of B / Molar mass of A
- Substituting the given values: 3.0 / 1.5 * 2x / x = 2
Calculating the ratio of pressure:
- The pressure is directly proportional to the number of moles of gas and the temperature
- Since the temperature is the same for both gases, the ratio of pressure is the same as the ratio of the number of moles
- Therefore, the ratio of pressure exerted by gases A and B is 2
Therefore, the correct answer is:
Ratio of pressure exerted by gases A and B = 2
- Volume of flask containing gas A = 0.5 dm3
- Volume of flask containing gas B = 1 dm3
- Density of gas A = 3.0 gm dm-3
- Density of gas B = 1.5 gm dm-3
- Molar mass of A = 1/2 of B
Calculating the number of moles:
- Number of moles of gas A = Mass / Molar mass = Density * Volume / Molar mass
- Number of moles of gas B = Density * Volume / Molar mass
Given that the molar mass of A is half of B:
- Let the molar mass of gas A be x, then the molar mass of gas B = 2x
Calculating the ratio of the number of moles:
- Number of moles of A / Number of moles of B = (Density of A * Volume) / Molar mass of A / (Density of B * Volume) / Molar mass of B
- This simplifies to: Density of A / Density of B * Molar mass of B / Molar mass of A
- Substituting the given values: 3.0 / 1.5 * 2x / x = 2
Calculating the ratio of pressure:
- The pressure is directly proportional to the number of moles of gas and the temperature
- Since the temperature is the same for both gases, the ratio of pressure is the same as the ratio of the number of moles
- Therefore, the ratio of pressure exerted by gases A and B is 2
Therefore, the correct answer is:
Ratio of pressure exerted by gases A and B = 2
