Solve the all given parts of following question:
Question: Most of earth's atmosphere is the gas nitrogen (N2molecules). The coldest natural temperature ever observed on earth was -129 °C, while the warmest was 58 °C.
Part A: What is the molecular mass, in kilograms, of the N2gas? Remember that N has a mass of 14 u, so N2has a mass of 28 u?
Part B: What is the root-mean-square speed in m/s of the nitrogen molecules at a temperature of -129 °C?
Part C: What is the root-mean-square speed in m/s of the nitrogen molecules at a temperature of 58 °C?
Part D: Convert the answers for parts B and C to miles per hour.
I am having a hard time understanding these questions. So if you answer please explain how you found the answers.
