The correct value of the gas constant R is close to

Options

A. `0.085 "litre atmosphere K"`
B. `0.082 "litre atmosphere" K^(-1) mol^(-1)`
C. `0.082 "litre - atmosphere"^(-1) K "mole"^(-1)`
D. `0.082 "litre"^(-1) "atmosphere"^(-1)K "mol"`

Answer

B

Explanation

`R = (PV)/(nT)` (at N.T.P)
Where `P = 1 atm, V = 22.4 lit , n = 1 mol , T = 273 K`
`= (1 xx 22.4)/(1 xx 273) = 0.082` litre atmosphere `K^(-1) mol^(-1)`
