For metal A
Heat absorbed by water = Heat released by metal
Mass of water x Cpw x temperature change = Mass of metal x Cpm x temperature change
90g x 4.184 J/g-°C x 3.4°C = 50g x Cpm x (100-28.4)°C
Cpm = 1,280.304/3,580
= 0.3576 J/g-°C
For metal Z
Heat absorbed by water = Heat released by metal
Mass of water x Cpw x temperature change = Mass of metal x Cpm x temperature change
90g x 4.184 J/g-°C x 3.1°C = 50g x Cpm x (100-28.1)°C
Cpm = 1,280.304/3,595
= 0.3561 J/g-°C
metal A has the higher specific heat

please help me. Thanks
A piece of copper metal weighing 36.3 g is initially at 100.0 degree C. It is dropped into a coffee cup calorimeter containing 50.0 g of water at a temperature of 20.0 degree C. After stirring, the final temperature of both copper and water is 25.0 degree C. Assuming no heat losses, an that the specific heat capacity of water is 4.184 J/g degreeC, what is the specific heat capacity of the copper in J/g degreeC?

PART A: A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in calorimeter is determined to be 19.6 °C. To this is added 50.0 mL of water that was originally a temperature of 54.5 °C. A careful plot of the recorded temperature established T0 as 31.1 °C. What is the calorimeter constant (J/°C)? DensityH2O = 1.00 g/mL Specific HeatH2O = 4.184 J/g·°C PART...
