Question

calculate the density of SO2 gas in g/dm3 at 25°c and 300 torr pressure.​

Answer 1

Answer:

The density of SO₂ at 25°C and 300torr is 1.02g/dm³.

Explanation:

Given,

         Temperature, T = 25°C = 25 + 273 = 298K

                pressure, P =​ 300torr = 300/760 = 0.39atm

molar mass of SO₂, M = 32+2×16 = 64g/mol.

          gas constant, R = 0.0821L.atm.mol⁻¹.K⁻¹

The density is given by

         d = PM/RT

substituting the values P, M, R, and T

⇒      d  = (0.39×64) / (0.0821×298)

⇒          = 1.02g/L = 1.02g/dm³

Hence, the density of SO₂ is 1.02g/dm³
