How many atoms are in the element copper and in the element carbon and in the element aluminum and how many atoms are in baking soda and how many atoms are in a sugar cube?
There are no "atoms in an element," but rather atoms OF an
element. If you are trying to find the number of atoms in a sample
of a pure element you divide its weight by its molar mass and then
multiply by 6.022 x 10^23 to get the answer in atoms. The answer
options are 2,3, or 4.
