I think the correct answer is Hemoglobin. Hemoglobin is necessary for the transport of oxygen by an erythrocyte. It is a protein molecule found in red blood cells made of four subunits; two alpha subunits and two beta subunits. This protein is responsible for carrying of oxygen to body cells and tissues, and carbon dioxide to the lungs.
Explanation:
There are 6.022x1023 molecules in 1 mole of SO3 (Avogadro's number) so in 0.25 moles, there are (0.25)(6.022x1023) molecules in the 0.25 moles of SO3. or 1.506x1023 molecules per 0.25 moles of SO3.
There is one atom of sulfur in each molecule of SO3. So there are 1.506x1023 atoms of sulfur in 0.25 moles of SO3.
