Answer:
the energy produced or released = 2.4 X (-1790) = -4296 kJ
Explanation:
In the given question the heat of combustion is given as H°rxn = −1790 kJ
Thus when one mole of acetone undergoes complete combustion, it gives this much of energy.
The volume of acetone present in nail polish remover = 177 mL
The density of acetone = 0.788 g/mL
The mass of acetone present in nail polish remover = density X volume
the mass of acetone = 0.788 X 177 = 139.48 grams
the moles of acetone present = [tex]\frac{mass}{molarmass}=\frac{139.48}{58} =2.4 mol[/tex]
The energy produced = moles present X enthalpy of reaction
the energy produced or released = 2.4 X (-1790) = -4296 kJ
