Answer 2

Gas Density Calculation

To determine the formula of the unknown gas, we can use the concept of relative density compared to air. The relative density of a gas compared to air can be calculated using the formula:

Relative Density = Density of Gas / Density of Air

Given that the relative density of the unknown gas compared to air is 2.2, we can use the density of air as a reference point, which is approximately 1.225 kg/m³ at 15°C and 1 atm pressure.

Using the given information, we can calculate the density of the unknown gas and then determine its formula.

Calculation

The density of the unknown gas can be calculated using the formula:

Density of Gas = Relative Density * Density of Air

Substituting the given values: Density of Gas = 2.2 * 1.225 kg/m³

Density of Gas ≈ 2.695 kg/m³

Conclusion

Based on the calculated density of the unknown gas, we can determine its formula using the ideal gas law, which states that the density of a gas is directly proportional to its molar mass.

The molar mass of the gas can be calculated using the formula:

Molar Mass = (Density * (22.4 L/mol)) / (0.0821 atm L / mol K * Temperature in Kelvin)

By determining the molar mass, we can then identify the gas and its formula.
