Calculate the mass of carbon present in 2 g of carbon dioxide.

Explanation

To calculate the mass of carbon present in 2 grams of carbon dioxide (CO₂), we can follow these steps:

### Step 1: Determine the mass ratio of carbon to carbon dioxide
We know that carbon dioxide (CO₂) is composed of carbon (C) and oxygen (O) in a fixed mass ratio. The molar mass of carbon is approximately 12 g/mol, and the molar mass of oxygen is approximately 16 g/mol. Since CO₂ contains one carbon atom and two oxygen atoms, we can calculate the molar mass of CO₂:

\[ \text{Molar mass of CO₂} = \text{mass of C} + 2 \times \text{mass of O} = 12 \, \text{g/mol} + 2 \times 16 \, \text{g/mol} = 12 + 32 = 44 \, \text{g/mol} \]
