Answer:
5.46 8 x 10²³ molecules.
Explanation:
- Knowing that every one mole of a substance contains Avogadro's no. of molecules (NA = 6.022 x 10²³).
Using cross multiplication:
1.0 mole → 6.022 x 10²³ molecules.
9.08 x 10⁻¹ mole → ??? molecules.
∴ The no. of molecules of CO₂ are in 9.08 x 10⁻¹ mol = (6.022 x 10²³ molecules) ( 9.08 x 10⁻¹ mole) / (1.0 mol) = 5.46 8 x 10²³ molecules.
