How many molecules of carbon dioxide are in 9.080 x 10 ^-1 mol?

5.46 8 x 10²³ molecules.

Explanation:

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.
