If density of a gas in closed cylinder is

3.5g{L^{ - 1}}

at 4.1 atm pressure and

{127^0}C

temperature then molar mass of the gas will be

\left( {R = 0.082\,L\,atm\,{K^{ - 1}}\,mo{l^{ - 1}}} \right)

View answer and explanation

Correct option: B

28\,g\,mo{l^{ - 1}}

Option B (

28\,g\,mo{l^{ - 1}}

) is correct because it is calculated using the ideal gas law and the given density, pressure, and temperature.
