Answer
$4.30\times10^{3}$ kJ heat is released.
Work Step by Step
Heat= $177\,mL\times\frac{0.788\,g\, acetone}{1\,mL}\times\frac{1\,mol\, acetone}{58.08\,g\, acetone}\times\frac{-1790\,kJ}{1\,mol\, acetone}$
$=-4.30\times10^{3}\,kJ$
Negative sign indicates that the heat is released and can be neglected.
Heat released= $4.30\times10^{3}\,kJ$
