Understanding Carbon Monoxide and Atoms

This video tutorial explains how to determine the number of atoms in carbon monoxide (CO). It begins by identifying the elements in CO, carbon and oxygen, and explains that each has one atom since no subscript is present. The video then calculates the total number of atoms in CO as two. It further explores how to find the number of carbon and oxygen atoms in one mole of CO by multiplying by Avogadro's number, resulting in 6.02 x 10^23 atoms for each element. The tutorial concludes with a brief summary.
