Calculate the number of atoms of nitrogen in 0.1 mole of N2 gas (N = 14u).6.022×10236.022×10221.2044×10231.2044×1022

To calculate the number of atoms of nitrogen in 0.1 mole of N2 gas, you need to understand that one mole of any substance contains Avogadro's number of particles, which is 6.022 x 10^23.

In one molecule of N2 gas, there are 2 nitrogen atoms. Therefore, in one mole of N2 gas, there are 2 moles of nitrogen atoms.

So, in 0.1 mole of N2 gas, there would be 0.1 x 2 = 0.2 moles of nitrogen atoms.

To find the number of atoms, you multiply the number of moles by Avogadro's number:

0.2 moles x 6.022 x 10^23 atoms/mole = 1.2044 x 10^23 atoms

So, there are 1.2044 x 10^23 atoms of nitrogen in 0.1 mole of N2 gas.
