13.9 mol of helium is confined to a 19 L vessel at a pressure of 7 atm. Boltzmann’s constant is 1.38 × 10−23 J/K, and the universal gas constant is 8.31 J/K. Find the average kinetic energy of a helium molecule of mass 5.34 × 10−26 kg. Answer in units of J.
For the gas constant, use R = 8.314 J/mol-K For Avogadro's number, use N_0 = 6.022 times 10^23 molecules. Be careful of units! All the conversions you need are in the information section of the lab. Suppose the volume of the syringe is 47.5 cc. You measure the pressure as 1.58 atm, and the temperature as 19.8 degree C. Assume: the diameter of the plunger on the syringe is 1.44 cm. Find the number of moles of gas in the...
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the sume kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed 3RT rms speed where R 8.314 J/(mol-K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram-meter squared per second squared (kg-m2/s2) What is the rms speed of O, molecules...
