Question

What is the density of Iodine gas at 2.36 atm and 65.0 C?

Answer 1

The density : 21.63 g/L

Further explanation

The gas equation can be written

`\large {\boxed {\bold {PV = nRT}}}`

where

P = pressure, atm

V = volume, liter

n = number of moles

R = gas constant = 0.08206 L.atm / mol K

T = temperature, Kelvin

T = 65+273=338 K

P=2.36 atm

MW Iodine gas (I₂)=254

The density :

`\tt \rho=(P* MW)/(RT)\\\\\rho=(2.36* 254)/(0.082* 338)=21.63~g/L`
