42.6897 grams of carbon dioxide would be produced from the following reaction, if 175 kJ of energy is given off.
How do we calculate moles?
The mole (symbol mol) is the SI base unit of material quantity. The amount of substance in an object or sample is a measure of how many elementary entities of a certain substance are present.
Given chemical reaction is:
[tex]2CO + O_2[/tex] → [tex]2 CO_2[/tex]
From the stoichiometry of the reaction, it is clear that 2 moles of carbon dioxide are produced.
Actual moles will be calculated by using the enthalpy and energy value as:
Actual moles of [tex]CO_2[/tex] = 275kJ × ([tex]\frac{2 mol}{566 kJ}[/tex]) = 0.97 moles.
Grams of carbon dioxide = moles X molar mass of carbon dioxide.
Grams of carbon dioxide = 0.97 X 44.01 g/mol
Grams of carbon dioxide = 42.6897 g
