Calculate the number of CO2 molecules (NCO2) in 0.0693 mol of CO2

0.42*10²³ molecules of CO₂.

Explanation:

Given dа ta:

Number of moles of CO₂ = 0.0693 mol

Number of molecules of CO₂ = ?

Solution:

The given problem can be solve by using the Avogadro number.

Avogadro number is the number of atoms, ions and molecules in one gram atom of element, one gram molecule of compound and one gram ion of substance.

The number 6.022*1023 is called Avogadro number.

1 mole of CO₂ contain 6.02 * 10²³ molecules of CO₂

0.0693 moles of CO₂ contain = 0.42*10²³ molecules of CO₂

0.0693 * 6.02 * 10²³ = 0.42*10²³
