Consider the molecular models shown in the figure below (gray = C, white = H, red = O, blue = N, yellow-green = F). Determine the number of moles for Compound I and Compound II if each has a mass of 28.0 grams.

• A. Compound 1 = 0.528 moles
  Compound 2 = 0.417 moles
• B. Compound 1 = 0.596 moles
  Compound 2 = 0.424 moles
• C. Compound 1 = 1.24 moles
  Compound 2 = 1.22 moles
• D. Compound 1 = 0.424 moles
  Compound 2 = 0.417 moles

Answer: (D)
