Calculate the final equilibrium temperature when 10.0 grams of steam initially at 100 degree C is mixed with 450 grams of liquid water and 110 grams of ice at 0 degree C in a calorimeter. That is, the liquid water AND the ice are initially at 0 degree C. Ignore any heat energy exchanges with the calorimeter and the surroundings. If you conclude that the final temperature of the system is 0 degree C, then what mass of ice remains,...

Question 16 (8 points) Steam at 100°C was passed into a flask immersed in 937 g of water at 21°C, where the steam condensed to water at 100°C. How many grams of steam must have condensed if the temperature of the water around the flask was raised to 85°C? Assume that the condensed water remains at 100°C. The heat of vaporization of water is 40.7 kJ/mol and the specific heat is 4.18 J/(g°C).
