Question

3.000 g of C₂H4O₂ (formula weight = 60.05 g/mol) was burned in a soda can calorimetry experiment (open to the atmosphere). The temperature of the lab was 278.0 K and the pressure was 1.010 bar. The soda can is made of 14.70 g of aluminum (Cs = 0.890 J/g°C) and contains 125.0 g water (Cs = 4.184 J/g°C).Calculate the final temperature of the water after all 3.000 g of acetic acid has been consumed.
