Question

Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of substance A is 6.34 g and its initial temperature is 20.2 ∘C . The mass of substance B is 25.3 g and its initial temperature is 52.8 ∘C. The final temperature of both substances at thermal equilibrium is 46.2 ∘C.

If the specific heat capacity of substance B is 1.17 J/(g⋅∘C), what is the specific heat capacity of substance A?

Express your answer in joules per gram per degree Celsius.
