Calculate the amount of heat absorbed during the decomposition of 440 g of carbon dioxide

The solution to this problem can be found below:
Given: m (CO2) = 440 g.
Find Q2

Decision:
440 g x kJ.
CO2 = C + O2 – 394 kJ.
44 g
x = 440 g x 394 kJ / 44g. = 3940 kJ.

As a result, we get the amount of heat that was absorbed during decomposition
