Question

Arrange the gases from most dense to least dense at a given temperature and pressure. Most dense SF NH3 COâ‚‚ Hâ‚‚ 0â‚‚ Least dense

Answer 1

To arrange these gases from most dense to least dense at a given temperature and pressure, we can use the concept of molar mass (the mass of one mole of a substance) to estimate their relative densities. The gas with the highest molar mass will be the most dense, while the gas with the lowest molar mass will be the least dense. Here are the gases arranged in order from most dense to least dense:

1. SF6 (Sulfur Hexafluoride) - Molar Mass: Approximately 146.06 g/mol

2. CO2 (Carbon Dioxide) - Molar Mass: Approximately 44.01 g/mol

3. NH3 (Ammonia) - Molar Mass: Approximately 17.03 g/mol

4. H2 (Hydrogen) - Molar Mass: Approximately 2.02 g/mol

5. O2 (Oxygen) - Molar Mass: Approximately 32.00 g/mol

So, from most dense to least dense:

SF6 > CO2 > NH3 > O2 > H2
