Regardless of whether we are counting atoms or molecules, the number of either unit in a mole will be the same. The number a mole represents can be thought of in the same way we think of a dozen cookies or a dozen eggs. What we count changes but a dozen always means 12 ...
Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles:...

To do this, look up atomic masses on the periodic table and use the formula mass to know how many atoms of each element are in a compound. Remember, subscripts in a formula indicate the number of atoms. If there is no subscript, it means there is only one atom of that element in th...
