Step 1: Identify the molar masses of each element in the compound.
The molar mass of carbon (C) is approximately 12.01 g/mol, and the molar mass of oxygen (O) is approximately 16.00 g/mol.
Step 2: Calculate the molar mass of the entire molecule.
Since carbon dioxide (CO2) consists of one carbon atom and two oxygen atoms, we can calculate the molar mass as follows: \text{Molar mass of CO}_2 = \text{Molar mass of C} + 2 \times \text{Molar mass of O} = 12.01 \text{ g/mol} + 2 \times 16.00 \text{ g/mol}
Final Answer
The molar mass of carbon dioxide (CO2) is 44.0 g/mol (A).
