What is the weight percent of oxygen in Glucose ? 

Explanation

To find the weight percent of oxygen in glucose (C6H12O6), we can follow these steps:

### Step 1: Determine the molecular formula of glucose.
The molecular formula of glucose is C6H12O6.

### Step 2: Calculate the molar mass of glucose.
To calculate the molar mass, we need to sum the atomic masses of all the atoms in the molecular formula:
- Carbon (C): 6 atoms × 12 g/mol = 72 g/mol
