Vedclass · Answer

(B) The number of moles of hydrogen is calculated as $n_{H_2} = \frac{3 \ g}{2 \ g \ mol^{-1}} = 1.5 \ mol$. The number of moles of oxygen is calculated as $n_{O_2} = \frac{80 \ g}{32 \ g \ mol^{-1}} = 2.5 \ mol$. The total number of moles in the gaseous mixture is $n = 1.5 + 2.5 = 4 \ mol$. The total kinetic energy of an ideal gas mixture is given by the formula $KE = \frac{3}{2} n R T$. Substituting the values,we get $KE = \frac{3}{2} 	imes 4 	imes R T = 6RT$.

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 $T(K)$ (in $RT$)?
