Let’s write the equation of this reaction:

CH4 + 2O2 = CO2 + 2H2O

Let’s find the amount of methane substance:

v (CH4) = m (CH4) / M (CH4) = 112/16 = 7 (mol).

According to the reaction equation, from 1 mol of CH4, 1 mol of CO2 is formed, therefore:

v (CO2) = v (CH4) = 7 (mol).

Thus, the volume of the formed carbon dioxide, measured at normal conditions:

V (CO2) = v (CO2) * Vm = 7 * 22.4 = 156.8 (L).

Answer: 156.8 liters.
