Which one of the following is the kinetic energy of a gaseous mixture containing 3 ~g of hydrogen and 80 ~g of oxygen at temperature T(K) ?

Step-by-step solution

Number of moles of hydrogen = 3 g 2 g ~mol ⁻¹ =1.5 Number of moles of oxygen = 80 ~g 32 ~g ~mol ⁻¹ =2.5=2.5 Total number of moles in gaseous mixture of hydrogen and oxygen, aligned & n=1.5+2.5=4 & KE = 3 2 n R T= 3 2 4 R T=6 R T aligned
