The mean free path of nitrogen molecules at 2.3°c and 1.28 atm is 1.51 x 10-5 cm. at this temperature and pressure there are 3.41 x 1019 molecules/cm3. what is the molecular diameter?

Answer : The molecular diameter is, [/tex]

Explanation :

Formula used for mean free path :

where,

= Mean free path =

d = diameter of molecule = ?

= number of molecules per unit volume  =

Now put all the given values in this formula, we get:

[/tex]

Therefore, the molecular diameter is, [/tex]

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
