A Few Reminders:
Always use a quality Periodic Table when solving problems for
this course, such as the one posted to Blackboard. Do not use
12 g/mol as the atomic weight for carbon ... 12.0107 g/mol is
far more precise.
Also, always include units in your work, and don't forget to
watch the significant digits in your computations.

Expert Solution
Step 1
There is error in calculation of mass of oxygen
Mass of O =0.0638-(0.0396+0.00664)
= 0.01756 g
Moles of O = 0.01756/16
= 0.0010975 mol
