Question

How many moles of carbon dioxide do you have if you have
1.23x10^23 particles of carbon dioxide?

Answer 1

Answer:  0.204 mol

Explanation:

Moles = # of particles ÷ Avogadro's Number

          =  (1.23 × 10²³ particles) ÷ (6.022 × 10²³ particles/mol)

          =  0.204 mol

∴ the 1.23 × 10²³ particles of carbon dioxide ≡ 0.204 mol
