ImTwo substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of substance A is 6.44 g and its initial temperature is 20.3 oC. The mass of substance B is 25.1 g and its initial temperature is 52.8 oC. The final temperature of both substances at thermal equilibrium is 46.7 oC. If the specific heat capacity of substance B is 1.17 J/g⋅oC, what is the specific heat capacity of substance A
