Enter your answer in the provided box. At a local convenience store, you purchase a cup of coffee, but, at 98.4°C, it is too hot to drink. You add 20.2 g of ice that is −2.2°C to the 248 mL of coffee. What is the final temperature of the coffee? (Assume the heat capacity and density of the coffee are the same as water and the coffee cup is well insulated.)
