Molar Mass Of Carbon Dioxide
Defining Molar Mass
Molar mass denotes the weight of one mole of a specific substance, usually expressed in grams per mole (g/mol). In the case of carbon dioxide (CO2), the mol mass represents the combined mass of one mole of carbon (C) atoms and two moles of oxygen (O) atoms.
The Calculation
To determine the mol mass of carbon dioxide, we need to sum the atomic masses of its constituent elements, carbon (C) and oxygen (O), using their respective atomic masses found on the periodic table. The molar mass of carbon is approximately 12.01 g/mol, while the molar mass of oxygen is approximately 16.00 g/mol.
Using these values, we can calculate the molar mass of CO2 as follows:
Molar Mass of CO2 = (Molar Mass of C) + 2 × (Molar Mass of O) Molar Mass of CO2 = (12.01 g/mol) + 2 × (16.00 g/mol) Molar Mass of CO2 ≈ 44.01 g/mol
So, the mol mass of carbon dioxide (CO2) is approximately 44.01 grams per mole.
