The kinetic energy of translation of the molecules in 50g of CO₂ gas at 17°C is : 

$$\begin{gathered} (\mathrm{KE}{)}_{\text{Transataional }}=\left[\frac{3}{2}\mathrm{KT}\right]\times \mathrm{no}. \mathrm{of} \mathrm{molecule} \\ \text{ No. of molecule }=\left[\frac{50}{44}\times 6.023\times {10}^{23}\right] \\ (\mathrm{KE}{)}_{\text{Translational }}=4108.644\mathrm{J} \end{gathered}$$
