Argon $(Ar)$ is a monatomic gas. What numerical value would you expect to calculate ior the molar specific heat at constant volume $(C_V)$ for Argon in units of $\frac{J}{\text{m}\text{o}\text{l}\text{e}*K}?$

a$.16\mathrm{.}6.$

b$.8\mathrm{.}31.$

$C_v=\frac{3}{2}R$

c$.20\mathrm{.}8.$

$($a$.)12\mathrm{.}5$

$=\frac{3}{2}(8\mathrm{.}314\frac{J}{m}ol*k)$

e$.24\mathrm{.}9.$
