10. In an experiment to determine the specific heat capacity of a certain metal, a student obtained the values given below; Mass of water Mw = 44.3g Mass of calorimeter, Mc = 58.7g Initial temperature of water before boiling, T₂= 18.4 °C Final temperature reached by the heated water, T₁= 85.4 °C Final temperature reached by the mixture (water+ calorimeter+ specimen metal), TF = 20.2 °C Calculate the specific heat capacity, C₁ of the specimen metal using the equation; C₁= {[(MwCw+McCc) (TF-T2)] / M1(T1-TF)} Where; specific heat capacity of water, Cw=4186J/Kg K - specific heat capacity of the calorimeter, Cc= 386J/Kg K Mass of the specimen, M₁ = 17.4g

An unknown hot metal at 148.7°C with a mass of 49.6g was mixed with 28.61g of water at an initial temperature of 19.74°C.  A final temperature (for both water and metal) of 27.71°C was reached. In units of J/(g°C), what is the specific heat of the unknown metal?  Note: In the space below, please enter you numerical answer.  Do not enter any units.  If you enter units, your answer will be marked as incorrect.
