A block of copper with a mass of 1.75 kg, initially at a temperature of 150.0°C, is in a well-insulated container. Water at a temperature of 26.0°C is added to the container, and the entire interior of the container is allowed to come to thermal equilibrium, where it reaches a final temperature of 66.0°C. What mass of water (in kg) was added? Assume any water turned to steam subsequently recondenses.  ?kg
