Question

answer with explanation please​

Answer 1

$\sf\large{\underline{\underline{Answer :}}}$

$\rm{Option—D)\:6.93\:cal\:{mol}^{-1}\:{K}^{-1}}$

$\sf\large{\underline{\underline{Explaination :}}}$

$\rm\dfrac{C_p}{C_v}=1.4$

$\rm{C_p=1.4C_v=1.4×20.8}$

$\rm{\:\:\:\:\:\:\:=29.12J/mol}$

$\rm{C_p=\dfrac{29.12}{4.2}=6.93}$
