When 5.00 g of acetone (C3H6O) burns in air, carbon dioxide gas and liquid water are formed. Enough heat is liberated to increase the temperature of 1.000 kg of water from 25.0◦C to 61.8◦C. The specific heat of water is 4.18 J/g-◦C
1. How many kJ of heat are liberated by the combustion described?
2. How many grams of acetone must be burned to liberate 5.00 kJ?
3. Write the thermochemical equation for the combustion of acetone.
4. What is ΔH◦f for acetone?
5. What volume of oxygen at 25◦C and 747 mm Hg is consumed when 25.00 kJ of heat are liberated?
