Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of substance A is 6.04g and its initial temperature is 20.6?C. The mass of substance B is 25.7g and its initial temperature is 52.0?C. The final temperature of both substances at thermal equilibrium is 46.9?C.

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