Question

Calculate how many moles of carbon dioxide are contained in 5.57 x 10²¹ molecules of CO₂

Answer 1

Answer:  0.00925 mol

Explanation:

Moles = # of molecules ÷ Avogadro's Number  

         =  (5.57 × 10²¹ molecules) ÷ (6.022 × 10²³ molecules/mol)  

         =  0.00925 mol

∴ the 5.57 x 10²¹ molecules of carbon dioxide ≡ 0.00925 mol
