TopicDetails
Chemical FormulaCO₂
Atomic Composition1 Carbon (C) atom and 2 Oxygen (O) atoms
Atomic Weight of Carbon (C)12.01 g/mol
Atomic Weight of Oxygen (O)16.00 g/mol
Molecular Weight of CO₂44.01 g/mol (calculated using the formula below)
Molecular Weight CalculationMolecularWeightofCO2Molecular Weight of CO₂MolecularWeightofCO2​ = (Atomic Weight of Carbon) + 2 × (Atomic Weight of Oxygen)
Molecular Weight Formula12.0112.0112.01 + 2 × 16.0016.0016.00 = 44.01 g/mol
Molar Mass44.01 g/mol
Common UsesCO₂ is used in various industries including food and beverages (carbonation), fire extinguishers, and as a refrigerant (dry ice).
State at Standard Temperature and Pressure (STP)Gas (colorless, odorless, and non-flammable)
Density of CO₂1.977 g/L at STP (0°C and 1 atm)
Boiling Point of CO₂-78.5°C (sublimes directly from solid to gas at standard pressure)
Role in the EnvironmentCO₂ is a key greenhouse gas that contributes to global warming; also vital for photosynthesis in plants.
CO₂ in the Human BodyCO₂ is a waste product of respiration and is exhaled from the lungs. High concentrations can lead to toxicity.
Industrial ProductionCO₂ is produced commercially by combustion of fossil fuels or as a by-product of fermentation and chemical processes.
Molecular StructureLinear structure with two double bonds between the carbon atom and the two oxygen atoms (O=C=O)
