What is the mass per cent of carbon in carbon dioxide?

Options

A. 0.00034
B. 0.2727
C. 0.034
D. 0.287

Explanation

To find the mass percent of carbon in carbon dioxide (CO₂), we can follow these steps:

### Step 1: Determine the molecular mass of carbon dioxide (CO₂)
- The molecular formula for carbon dioxide is CO₂, which consists of one carbon (C) atom and two oxygen (O) atoms.
- The atomic mass of carbon (C) is approximately 12 grams per mole.
- The atomic mass of oxygen (O) is approximately 16 grams per mole.
- Therefore, the molecular mass of CO₂ can be calculated as:
