Answer:
The answer to your question is 9.034 x 10²³ molecules
Explanation:
Data
number of molecules = ?
number of moles = 1.50
Process
To solve this problem, use Avogadro's number. This number relates 1 mol of a substance to 6.023 x 10²³ molecules.
1 mol of CO₂ --------------- 6.023 x 10 ²³ molecules
1.5 moles of CO₂ ---------- x
x = (1.5 x 6.023 x 10²³) / 1
x = 9.034 x 10²³ molecules
