Calculate the volume of carbon dioxide produced by the complete combustion of 2.4 carbon.

Given:
m (C) = 2.4 g

To find:
V (CO2) -?

Decision:
1) Write the equation of a chemical reaction:
C + O2 => CO2;
2) Using the periodic system of D.I.Mendeleev, calculate the molar mass C, which will be numerically equal to the molecular mass:
Mr (C) = Ar (C) = 12 g / mol;
3) Calculate the amount of substance C:
n (C) = m (C) / Mr (C) = 2.4 / 12 = 0.2 mol;
4) Determine the amount of substance CO2 (taking into account the coefficients in the reaction equation):
n (CO2) = n (C) = 0.2 mol;
5) Calculate the volume of CO2:
V (CO2) = n (CO2) * Vm = 0.2 * 22.4 = 4.48 liters.

Answer: The CO2 volume is 4.48 liters.
