Answer
(a) $3400J$
(b) $3400J$
(c) $3400J$
Work Step by Step
We can determine the required total translational kinetic energy as follows:
$E=\frac{3}{2}k_B TN_A$
We plug in the known values to obtain:
$E=\frac{3}{2}(1.38\times 10^{-23})273\times 6.02\times 10^{23}$
This simplifies to:
$E=3400J$
We know that the translational kinetic energy for 1 mole of hydrogen, helium and oxygen is same at STP.
