Calculate the root mean square velocity, vrms, of a molecule that has a molar mass, M, of 45.02 g/mol at a temperature of 40.56 °C using the equation below. For this calculation the gas constant, R, is expressed as 8.314 J/(mol*K) and the molar mass, M, needs to be converted to kg/mol. vrms=3RTM
Calculate the root-mean-square speed of uranium hexafluoride, UF6, at 388 K in units of m/s. (Round your answer to 3 significant figures.)
The molecules of a certain gas sample at 375 K have a root-mean-square (rms) speed of 271 m/s. Calculate the most probable speed and the mass of a molecule. Most probable speed: Number 0 m/s Molecular mass: Number
Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is the square root of the average of the squares of the speeds of all the gas molecules. What is the rms speed of a sample of O2 at 12.49 °C, in m/s? A typed answer is prefered. Answer should be in significant figures.
Calculate the root-mean-square (rms) speed (in m/s) of propane (C3H8) gas molecules at a temperature of 270 K.
Compute the root-mean-square speed of Ar molecules in a sample of argon gas at a temperature of 191°C.
5. Calculate the mean speed of a. chlorine molecules at 400 K. b. neon atoms at 350 K. c. If you used the root mean square speed formula instead of the mean speed formula, would your answers to parts a and b be smaller or larger? Explain.

Which would have the highest root mean square speed? Explain a) Ne at 300K b) Ne at 150K c) Ar at 300K d) Ar at 150k
EXAMPLE 6-14 Calculating a Root-Mean-Square Speed Which is the greater speed, that of a bullet fired from a high-powered M-16 rifle (2180 mi/h) or the root-mean-square speed of H2 molecules at 25 °C? Analyze This is a straightforward application of equation (6.19). We must use SI units: R = 8.3145JK mol- and M = 2.016 X 10-kg mol-1. Recall that 1 J = 1 kg m?s Solve Determine urms of H2 with equation (6.19). 3 x 8.3145 kg m’s 2...
