This seemingly simple question requires a deeper understanding of molecular composition, molar mass, and Avogadro’s number. Embark on a scientific journey to unravel the atomic realm of CO2 and uncover the intricacies of matter.

Carbon dioxide, a ubiquitous compound in Earth’s atmosphere, plays a crucial role in various biological and chemical processes. Determining the number of atoms in a given mass of CO2 is essential for comprehending its behavior and interactions.

1. Molecular Composition of Carbon Dioxide

Carbon dioxide (CO ₂) is a compound composed of carbon and oxygen atoms. It is a colorless, odorless gas that is essential for plant growth and plays a crucial role in the Earth’s atmosphere.

Chemical Formula and Atomic Composition

Chemical formula: CO ₂
Atomic composition: Each molecule of CO ₂contains one carbon atom and two oxygen atoms.

2. Molar Mass and Avogadro’s Number: How Many Atoms Are In 4.39 G Of Co2

Molar Mass

Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It is used to convert between the mass and the number of moles of a substance.

Avogadro’s Number

Avogadro’s number (N _A) is the number of atoms or molecules in one mole of a substance. It is equal to 6.022 × 10 ²³.

Molar Mass of CO₂

The molar mass of CO ₂is calculated by adding the atomic masses of carbon and oxygen:

Molar mass = (1 × 12.01 g/mol) + (2 × 16.00 g/mol) = 44.01 g/mol

3. Mass to Moles Conversion

To convert a given mass of CO ₂to moles, divide the mass by the molar mass:

Moles = Mass (g) / Molar mass (g/mol)

Calculating Moles of CO₂

To calculate the number of moles in 4.39 g of CO ₂:

Moles = 4.39 g / 44.01 g/mol = 0.0997 mol

4. Moles to Atoms Conversion

Relationship between Moles and Atoms

The number of atoms in a given number of moles can be calculated using Avogadro’s number:

Atoms = Moles × Avogadro’s number (N _A)

Calculating Atoms of CO₂, How many atoms are in 4.39 g of co2

To calculate the number of atoms in 4.39 g of CO ₂, first convert the mass to moles and then multiply by Avogadro’s number:

Atoms = 0.0997 mol × 6.022 × 10 ²³atoms/mol = 6.00 × 10 ²¹atoms
