Solve the each part of following question given below:

Question: On earth, STP is based on the average atmospheric pressure at the surface and on a phase change of water that occurs at an easily produced temperature, being only slightly cooler than the average air temperature. The atmosphere of Venus is almost entirely carbon dioxide (CO2), the pressure at the surface is a staggering 93 atm, and the average temperature is 470oC. Venusians scientists, if they existed, would certainly use the surface pressure as part of their definition of STP. To complete the definition, they would seek a phase change that occurs near the average temperature. Conveniently, the melting point of the element tellurium is 450oC. The radius of a CO2 molecule is 1.5×1010 m.

Part I: What is the rms speed of carbon dioxide molecules at Venusians STP based on this phase change in tellurium?

Part II: What is the mean free path of carbon dioxide molecules at Venusians STP based on this phase change in tellurium?

I am not able to get the correct answer please help me and express your answer to two significant figures and include the appropriate units.
