Suppose you have 20.81 g of water,initially at 25.00 oC, in a perfectly insulated container. You then add water which is at 83.71 oC tothe container until the combined sample of water has a temperature of 58.71 oC. What mass (in grams) of hot water was added? Do not include units (g) in your answer. The specific heat capacity of water is 4.184 J g-1oC-1.
