| 1. Let’s calculate the chemical amount of carbon dioxide:
n (CO2) = m (CO2): M (CO2);
M (CO2) = 12 + 2 * 16 = 44 g / mol;
n (CO2) = 4.4: 44 = 0.1 mol;
2. find the volume of gas:
V (CO2) = n (CO2) * Vm = 0.1 * 22.4 = 2.24 l;
3.Calculate the number of CO2 molecules:
N (CO2) = n (CO2) * Na = 0.1 * 6.02 * 10 ^ 23 = 6.02 * 10 ^ 22 molecules.
Answer: 0.1 mol, 2.24 L, 6.02 * 10 ^ 22 molecules.
