An unknown substance has a mass of 11.3 g . When the substance absorbs 1.017×102 J of heat, the temperature of the substance is raised from 25.0 ∘C to 45.0 ∘C . What is the most likely identity of the substance?

q = mcdT

101.7 = 11.3 g x specific heat x (45.0 - 25,0)
Solve for specific heat and compare with a table of specific heats to identify the substance.
