The density of SO₃ gas at 25 °C and 715 Torr is 3.08 g/L.
We want to calculate the density of SO₃ gas at 25 °C and 715 Torr.
What is density?
Density (ρ) is the ratio of the mass to the volume of a substance.
If we assume ideal behavior, we can calculate the density of SO₃ using the following expression.
ρ = P × M / R × T
where,
- P is the pressure of SO₃.
- M is the molar mass of SO₃.
- R is the ideal gas constant.
- T is the absolute temperature of SO₃.
To apply this formula, we need to convert 25 °C to Kelvin using the following expression.
K = °C + 273.15 = 25 °C + 273.15 = 298 K
The density of SO₃ is:
ρ = P × M / R × T
ρ = 715 Torr × (80.06 g/mol) / (62.4 mmHg.L/mol.K) × 298 K = 3.08 g/L
The density of SO₃ gas at 25 °C and 715 Torr is 3.08 g/L.
