The number of molecules present in 0.26 mole of carbon dioxide, CO₂ is 1.57×10²³ molecules

Avogadro's hypothesis

1 mole of CO₂ = 6.02×10²³ molecules

How to determine the molecules in 0.26 mole of  CO₂

1 mole of CO₂ = 6.02×10²³ molecules

Therefore,

0.26 mole of CO₂ = 0.26 × 6.02×10²³

0.26 mole of CO₂ = 1.57×10²³ molecules

Thus, 1.57×10²³ molecules are present in 0.26 mole of CO₂
