Canvas Classes · Accepted Answer

Strategy:
 For an organic compound containing C, H, and O, determine the masses of Carbon and Hydrogen from the combustion products. Subtract their sum from the total sample mass to find the mass of Oxygen, then calculate its percentage.

Step 1: Calculate masses of Carbon and Hydrogen
- Mass of .
- Mass of .

Step 2: Find mass of Oxygen by difference

Step 3: Calculate percentage
