temperature?

Question

near the surface of venus, the rms speed of carbon dioxide molecules (CO2) is 650 m/s. what is the temperature in K of the atmospere at that point

Answer 1

if u have Vrms i suppose u can use the following eq
Vrms = sqrt ( 3RT / M)
R = gas constant (8.31 J / mol K)
and
M is atomic mass (molecular mass) CO2 (44 g/mol)
so rearrange and solve for T
