Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of substance A is 6.27 g and its initial temperature is 20.9 ∘C . The mass of substance B is 26.1 g and its initial temperature is 52.7 ∘C. The final temperature of both substances at thermal equilibrium is 46.3 ∘C. If the specific heat capacity of substance B is 1.17 J/(g⋅∘C), what is the specific heat capacity of substance A?
