24. How many molecules are present in 1c
(0.5 Points)​

Answer 1

Answer:

A mole of a substance contains 6.022 x 1023 particles of that substance. This is Avogadro's number.

Answer 2

Explanation:

The volume of the gas is 1c.c=10−3L

∴ Number of moles of the gas is=22.410−3

Now,

Number of molecules=n×6.022×1023

∴   Number of Nitrogen Molecules = 22.410−3×6.023×1023

                                                      

                                                          = 2.67×1019
