Question

Calculate the energy of an air molecule at room temperature.. Full solution please... ​

Answer 1

Answer:

You can calculate how many molecules there are in a room, (4m x 3m x 3m = 24 m3) giving about 5 x 1026 molecules. This is in fact an estimate of the Avogadro number for a kilo-mole. A kilogram mole of any gas contains 6 x 1026molecules.

Answer 2

Explanation:

figure the total kinetic energy, you multiply the average kinetic energy by the number of molecules you have, which is nNA, where n is the number of moles:

NAk equals R, the universal gas constant, so this equation becomes the following
