Nitrogen and Oxygen in N2O5

The video tutorial explains how to determine the number of atoms in dinitrogen pentoxide (N2O5). It begins by identifying the elements in N2O5, which are nitrogen and oxygen, and explains the subscripts indicating the number of each atom. The total number of atoms in N2O5 is calculated by adding the nitrogen and oxygen atoms. The video further explains how to calculate the number of nitrogen atoms in one mole of N2O5 using Avogadro's number. The tutorial concludes with a brief thank you from Dr. B.
