A calorimeter, fabricated from 135.0 g of iron metal, thermallyinsulated from its surroundings, contains 173.0 g of water. Both the calorimeter and the water are at an initial temperature of21.25°C. A 64.0-g sample of an unidentified substance is heatedto 98.0°C and then placed into the water inside thecalorimeter. After a short time the temperature of the calorimeterand its contents equilibrate at 25.30°C.

The specific heat of water is 4.18 J/g/K.
The specific heat of iron metal is 0.444 J/g/K.
What is the specific heat of the unidentified substance?
