  A) They represent the same thing.
  B) The formula mass of a substance is the sum of the atomic masses of the elements is its chemical formula. The atomic mass is the mass of a single atom.
  C) The atomic mass of a substance is the sum of the formula masses of the elements is its chemical formula. The atomic mass is the mass of a single atom.
  D) The formula mass is the mass of the chemical formula and the atomic mass is the mass of the molecule.

Question 2

How are oxygen molecules attracted to water molecules?
 
  A) The attraction between oxygen and water molecules is a classic example of dipole-dipole interaction.
  B) The hydrogen bonding in water causes the attraction of the oxygen atoms in the molecule to water.
  C) As a water molecule is brought close to an oxygen molecule an induced dipole results in the molecule causing the attraction.
  D) The attraction of oxygen and water molecules for one another is part of the common atom effect. Since both molecules contain oxygen, there is a built-in attraction.
