42.6897 grams of carbon dioxide would be produced from the following reaction, if 175 kJ of energy is given off.
<h3>How do we calculate moles?</h3>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:
→
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 = 275kJ × (
) = 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
