Acube of tin with a mass of 1.90 kg, initially at a temperature of 150.0°c, is in a well-insulated container.
water at a temperature of 20.0°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 60.0°c.

what mass of water (in kg) was added? assume any water turned to steam subsequently recondenses.
