Question

Calculate the number of atoms of nitrogen in 0.1 mole of N2 gas

Answer 1

Answer:

12.044x10²²

Explanation:

Given,

0.1 mole of N2 gas.

We know that,

=> 1 mol of N2 has 6.022x10²³ molecules of N2

=> 0.1 mol of N2 has 6.022x10²² molecules of N2

Now each N2 molecules has 2 atom of Nitrogen as it's a diatomic molecule.

So the no. of atoms in 0.1 mol of N2 gas is:

=> 6.022x10²² x 2

=> 12.044x10²² atoms
