Hello I'm stuck on my chemistry lab report.
a. calculate the heat gained by the water in the calorimeter (qwater) after adding the aluminum.
b. calculate the heat gained by the calorimeter (qcal) after adding aluminum.
c. using results from questions a and b, calculate the heat lost by the aluminum (qmetal).
d. calculate the specific heat capacity of aluminum in J/gk.
e. determine percent error in the value of the heat capacity of aluminum by comparing it to its literature value.
Given:
mass of al: 50.17 g
temp of boiling water: 98.7 degrees celcius
volume of water: 50 ml
temperature of water at room temp: 23.9 degrees celcius
final temp of the system: 31.7 degrees celcius
