Answer 2

Calculating the Number of Molecules in Carbon Dioxide (CO2) with a Mass of 12

To calculate the number of molecules in carbon dioxide (CO2) with a mass of 12, we can use the concept of molar mass and Avogadro's number.

Molar Mass of CO2: The molar mass of carbon dioxide (CO2) is approximately 44.01 grams per mole.

Using the Molar Mass: We can use the molar mass to calculate the number of moles in 12 grams of CO2.

Avogadro's Number: Avogadro's number is approximately 6.022 x 10^23, which represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance.

Calculation:

Using the molar mass of CO2 and Avogadro's number, we can calculate the number of molecules in 12 grams of CO2.

Calculation Formula: Number of moles = Mass / Molar mass Number of molecules = Number of moles * Avogadro's number

Calculation: Number of moles = 12 g / 44.01 g/mol Number of molecules = Number of moles * Avogadro's number

Result: The number of molecules in 12 grams of CO2 can be calculated using the above formula.
