To determine whether a shiny gold-colored rock is actually gold, a chemistry student decides to measure its heat capacity. She first weighs the rock and finds it has a mass of 4.7 g. She then finds that upon absorption of 52.7 J of heat, the temperature of the rock rises from 25 ∘C to 57 ∘C. Find the specific heat capacity of the substance composing the rock. Express the specific heat capacity in joules per gram-Celsius to two decimal places....
