A 57.1 g piece of zinc (Csp = 0.388 J/g · °C), initially at 285.8 °C, is added to 155.3 g of a liquid, initially at 22.1 °C, in an insulated container. The final temperature of the metal–liquid mixture at equilibrium is 36.7 °C. What is the identity of the liquid? Neglect the heat capacity of the container.
