C3H6O + 4O2 --> 3CO2(g) + 3H2O(g) deltaH= -1790kJ

Question

the density of C3H6O is 0.79g/mL. HOw much heat is released by the combustion of 150mL of acetone?

Answer 1

grams acetone = volume x density = approx 115 grams but you need a more accurate number than that.

So you get 1790 kJ for 58 g C3H6O; how much will you get from 115 g.

1790 x (115/58) = ? kJ released.
