Question

calculate the pressure of a gas whose molar mass is 29.3 g mol , having density 1.29 kg at 273 K temperature.​

Answer 1

Answer:

100.22 Pa

Explanation:

Given :

Molar mass ( M )= 29.3 g / mol

Density ( d ) = 1.29 kg / m³

Temperature ( T ) = 273 K

We have value of R ( universal gas constant ) = 8.314 Pa m³ K⁻¹ mol⁻¹

We have to find Pressure :

We have :

P = d R T / M

Putting values here :

P = 1.29 × 8.314 × 273 / 29.3

P = 2,926.53 / 29.2 Pa

P = 100.22 Pa.

Hence the pressure of a gas is  100.22 Pa .
