C

_{v}=3/2R, where R is the gas constant. The heat capacity at constant volume of a gas is measured to be 43.58kJK

^{-1}. How many kg-moles of the gas are present?

Iv tried looking in the lecture notes and in the textbook, but cant find anything of use.

Iv made an attempt and got 3.5kg-moles. Not sure that its right though. I used R=kN

_{A}, where k is Boltzmann constant and N

_{A}is Avogadros number.
