Write your answer as an exponential as described in the instructions.
An atom of neon has a radius Ne-38. pm and an average speed in the gas phase at 25°C of 350.m/s.
Suppose the speed of a neon atom at 25°C has been measured to within 0.10%. Calculate the smallest possible length of box inside of which the atom could be
known to be located with certainty.
Write your answer as a multiple of "Ne and round it to 2 significant figures. For example, if the smallest box the atom could be in turns out to be 42.0 times the
radius of an atom of neon, you would enter "42.Ne" as your answer.

- One process for decaffeinating coffee uses carbon dioxide ( M=44.0 g/mol) at a molar density of about 14,0 mol/m3 and a temperature of about 60 . (a) Is CO2 a solid, liquid, gas, or supercritical fluid under those conditions? (b) The van der Waals constants for carbon dioxide are a=0.3658 Pa m6/mol2 and b=4.286105 m3/mol. Using the van der Waals equation, estimate pressure of CO2 at that temperature and density. `arrow_forwardThe mean free path λ and the mean collision time T of molecules of a diatomic gas with molecular mass 6.00 x10^-25 kg and radius r=1.0x10^-10m are measured.From these microscopic data we can obtain macroscopic properties such as temperature T and pressure P?

(a) Calculate a numerical value for the isothermal compressibility kT = -+ (), for air for summer in Albuquerque under the conditions of 0.83 atm and 311 K (100 °F), assuming ideal gas behavior. (b) The speed of sound is related to the isothermal compressibility via 1 Vsound p KT where the adiabatic exponenty = 7/5. Evaluate this expression to find the speed of sound in air (in meters per second, or in mph). It is helpful to note that the mass density p = (kg/mole) and molar density, i.e. the number of moles per cubic meter, which is the ratio n/V. You can use the ideal gas law PV = nRT to write the ratio n/V in terms of your known pressure P and known temperature T. The gas constant R = 8.314 J/(mole-Kelvin) or alternatively R = 0.08206 (liter-atm)/(mole- K). Standard temperature and pressure are 0 degrees C (273.15 K) and 1 atm (1.013×105 N/m²). A good estimate of M for air can be found by taking 20% of the molecular weight of oxygen and adding this to 80% of the molecular weight…arrow_forward
