Let’s find the amount of substance carbon dioxide:

v (CO2) = V (CO2) / Vm = 5.6 / 22.4 = 0.25 (mol).

Let’s find the mass of carbon dioxide:

m (CO2) = v (CO2) * M (CO2) = 0.25 * 44 = 11 (g).

Let’s find the number of carbon dioxide molecules:

N (CO2) = v (CO2) * Na = 0.25 * 6.02 * 10 ^ 23 = 1.505 * 10 ^ 23 (molecules).
