Hydrogen-2 is an isotope of hydrogen, commonly called deuterium. Water that is composed of oxygen and deuterium atoms is called heavy water. Heavy water has many uses, including in nuclear reactors to slow down neutrons. The use of heavy water eliminates the need for enriched uranium. Which one of the following samples contains the fewest number of molecules? H is used as the symbol for hydrogen-1, and D is used as the symbol for hydrogen-2. 42 g of D₂O 39 g of D₂0 36 g of H₂O 2 moles of H₂O O 2 moles of D₂O
