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.
