At what temperature will the total kinetic energy of 0.30 mol of He be same as the total kinectic energy of 0.40 mol of Ar at 400 K ?

At what temperature will the total kinetic energy of 0.30 mol of He be

1.	At what temperature will the total kinetic energy of 0.30 mol of He be same as the total kinectic energy of 0.40 mol of Ar at 400 K ?
Answer» 400 K 300 K 533 K 573 K Solution :`K.E.=(3)/(2)NRT` `:. (3)/(2)xx.04xx400=(3)/(2)xx0.3xxT" or "T=533" K"`
