Question

Calculate the no. Of particles in 3 moles of N2.

Answer 1

Answer:

Number of particles = 18.066 * 10²³ molecules of N₂

                                   = 36.132 * 10²³ atoms of N

Explanation:

We know that,

Number of moles = $\dfrac{Number \ of \ particles}{Avogadro \ number}$

Hence,

Number of particles = Number of moles * Avogadro number

Given that,

Number of moles = 3

Avogadro number = 6.022 * 10²³

Substituting these values in we get,

Number of particles = 3 * 6.022 * 10²³

Number of particles = 18.066 * 10²³ molecules

Since 1 molecule N₂ contains 2 atoms of N,

1 molecule N₂ => 2 atoms of N

18.066 * 10²³ molecules N₂ => 2 * 18.066 * 10²³ atoms of N

                                             => 36.132 * 10²³ atoms of N
