The percentage of Carbon in `CO_(2)` is

Options

A. `27.27%`
B. `29.27%`
C. `30.27%`
D. `26.97%`

Explanation

To calculate the percentage of carbon in carbon dioxide (CO₂), we will follow these steps:

### Step 1: Identify the molecular formula of CO₂
The molecular formula of carbon dioxide is CO₂, which consists of one carbon atom and two oxygen atoms.

### Step 2: Determine the atomic masses
- The atomic mass of carbon (C) is approximately 12 g/mol.
- The atomic mass of oxygen (O) is approximately 16 g/mol.

### Step 3: Calculate the total mass of CO₂
To find the total mass of CO₂, we need to sum the masses of its constituent atoms:
- Mass of 1 carbon atom = 12 g/mol
- Mass of 2 oxygen atoms = 2 × 16 g/mol = 32 g/mol

Total mass of CO₂ = Mass of carbon + Mass of oxygen
Total mass of CO₂ = 12 g/mol + 32 g/mol = 44 g/mol

### Step 4: Calculate the percentage of carbon in CO₂
The percentage of carbon in CO₂ can be calculated using the formula:
\[ \text{Percentage of Carbon} = \left( \frac{\text{Mass of Carbon}}{\text{Total Mass of CO₂}} \right) \times 100 \]

Substituting the values we have:
\[ \text{Percentage of Carbon} = \left( \frac{12 \, \text{g/mol}}{44 \, \text{g/mol}} \right) \times 100 \]

### Step 5: Perform the calculation
Calculating the fraction:
\[ \frac{12}{44} = 0.2727 \]

Now, multiplying by 100 to get the percentage:
\[ 0.2727 \times 100 = 27.27\% \]

### Final Answer
The percentage of carbon in CO₂ is **27.27%**.
