Question

In the equation PV = nRT, which one cannot be the numerical value of R (A) 8.31 × 107 erg K-1 mol-1 (B) 8.31 × 107 dyne cm K-1 mol-1 (C) 8.31 JK-1 mol-1 (D) 8.31 atm. K-1 mol-1

(atm K-1 mol-1) is not a unit of R

Q. In the equation $P V = n RT$ , which one cannot be the numerical value of $R$

$8.31 \times 1 0^{7} er g K^{- 1} m o l^{- 1}$

$8.31 \times 1 0^{7}$ dyne $c m K^{- 1} m o l^{- 1}$

$8.31 J K^{- 1} m o l^{- 1}$

$8.31 a t m . K^{- 1} m o l^{- 1}$

$(a t m K^{- 1} m o l^{- 1})$ is not a unit of $R$
