Vedclass · Answer

(D) The universal gas constant $R$ has different values depending on the units used:$1$. In $SI$ units,$R = 8.314 \, J \, K^{-1} \, mol^{-1}$.$2$. In $CGS$ units,$1 \, J = 10^7 \, 	ext{ergs}$,so $R = 8.314 	imes 10^7 \, 	ext{ergs} \, K^{-1} \, mol^{-1}$.$3$. Since $1 \, J = 1 \, N \cdot m$ and $1 \, N = 10^5 \, 	ext{dynes}$,$1 \, J = 10^5 \, 	ext{dynes} 	imes 10^2 \, cm = 10^7 \, 	ext{dynes} \cdot cm$. Thus,$8.314 	imes 10^7 \, 	ext{dynes} \cdot cm \, K^{-1} \, mol^{-1}$ is also correct.$4$. In $L \cdot atm$ units,$R = 0.0821 \, L \cdot atm \, K^{-1} \, mol^{-1}$.Therefore,the value $8.31 \, L \cdot atm \, K^{-1} \, mol^{-1}$ is incorrect.

In the equation $PV = nRT$,which of the following is not equal to the numerical value of $R$?
