That is called condensation
The mass of reactant that would produce 800 Joules of heat is equal to 800 J × (1 kJ/1000 J)/(24.7 kJ/g).
<h3>How to calculate the mass of reactant?</h3>
In order to determine the mass of reactant that would produce 800 Joules of heat, we would set up a conversion equation as follows:
<u>Note:</u> 1 kJ is equal to 1000 Joules.
<u>Conversion:</u>
1 gram = 24.7 kJ
X gram = 800 Joules
Therefore, the mass of reactant that would produce 800 Joules of heat is given by:
Mass = Heat × (conversion factor/rate of heat)
Mass = 800 J × (1 kJ/1000 J)/(24.7 kJ/g).
