The number of molecules present in 2.10 moles of CO₂ is 1.264×10²⁴ molecules.
From Avogadro's hypothesis, we understood that:
1 mole of any substance = 6.02×10²³ molecules.
This implies that:
1 mole of CO₂ = 6.02×10²³ molecules
With the above information, we can obtain obtained the number of molecules in 2.10 moles of CO₂. This can be obtained as follow:
1 mole of CO₂ = 6.02×10²³ molecules
Therefore,
2.10 moles of CO₂ = 2.10 × 6.02×10²³
2.10 moles of CO₂ = 1.264×10²⁴ molecules
Thus, the number of molecules present in 2.10 moles of CO₂ is 1.264×10²⁴ molecules
