Canvas Classes · Accepted Answer

Strategy:
 Determine the total mass of Carbon produced (from ) and relate it to the percentage composition in the original sample. This allows us to find the total mass of  moles of the compound, and thus its molar mass.

Step 1: Find mass of Carbon produced
Moles of .
Since 1 mole  contains 1 mole Carbon, mass of .

Step 2: Calculate total mass of the compound sample
The compound contains  Carbon.

Step 3: Calculate Molar Mass (M)
We know  moles of the compound weigh .
