The specific heat at constant volume of an unknown solid is measured at high temperature to be 319.5Jkg(adsbygoogle = window.adsbygoogle || []).push({}); ^{-1}K^{-1}. Estimate its molecular weight.

Cv=3R

Attempt.

I used the above equation to get a mass of the solid to be 0.0128kg but I have no idea of what to do next!
