69. Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of substance A is 6.15g and its initial temperature is 20.5C. The mass of substance B is 25.2g and its initial temperature is 52.7C. The final temperature of both substances at thermal equilibrium is 46.7C. If the specific heat capacity of substance B is 1.17J/gC, what is the specific heat capacity of substance A
