Question

The specific heat capactiy of aluminum is 0.900 J/g 'C

a) Calculate the energy needed to raise the temperature of a 8.50 x 10^2 g block of Aluminum from 22.8'C to 94.6'C.

b) Calculate the molar heat capacity of aluminum

Answer 1

a. q=mcDT
where m is the mass of the sample, c is the specific heat of the sample and DT (delta T) is the change in temperature.

q = (8.50 X 10^2 g)(0.900 J/gC)(94.6-22.8 C)
q= 5.49 X 10^4 J

b. (0.900 j/g'C) X 28.98 g/mol = 26.1 J/mol 'C
