Current Attempt in Progress

Four tanks A$,$ B$,$ C$,$ and D are filled with monatomic ideal gases. For each tank, the mass of an individual atom and the rms speed of the atoms are expressed in terms of $m$ and $v_{rms}$ respectively $($see the table$).$ Suppose that $m=2\mathrm{.}62{10}^{-26}kg,$ and $v_{rms}=850\frac{m}{s}.$ Find the temperature of the gas in each tank.
