PROBLEM 73P

Consider the equation for the combustion of acetone (C3H6O), the main ingredient in nail polish remover:

C3H6O(l) + 4 O2(g) → 3 CO2(g) + 3 H2O(g) ΔHrxn = −1790 kJ

If a bottle of nail polish remover contains 155 g of acetone, how much heat is released by its complete combustion?

Solution 73P

Consider the below equation

C3H6O(l) + 4 O2(g) → 3 CO2(g) + 3 H2O(g) ΔHrxn = −1790 kJ

From the equation it is clear that 1 mole of acetone releases 1790 KJ of energy

Molecular mass of acetone is 123+61+161=58grams
