Which sample contains the largest number of oxygen atoms? Select one: a. 8.0 g of carbon dioxide b. 8.0 g of potassium chlorate
adell [148]

The sample with the largest number of oxygen atoms will be calcium perchlorate.

<h3>Number of atoms in a compound</h3>

Since we are not looking at the number of moles, the mass of the compounds has no bearing on the number of atoms of oxygen.

  • The chemical formula for carbon dioxide is CO_2. Thus, it has 2 atoms of oxygen.
  • The chemical formula for potassium chlorate is KClO_3. Thus, it has 3 oxygen atoms.
  • The chemical formula for calcium perchlorate is Ca(ClO_4)_2. Thus, it has 8 atoms of oxygen.
  • The chemical formula for sodium hydroxide is NaOH. Thus, it has 1 atom of oxygen.

Therefore, the compound with the largest number of oxygen atoms is calcium perchlorate.
