Two substances A and B, initially at different temperatures, come into contact, and reach thermal equilibrium at 46.7 degrees celsius. The mass of substance A is 1.65g and it is initially at a temperature of 20.5 degrees celsius. The mass of substances B is 25.2-g and it is initially at a temperature of 52.7 degrees celsius. If the specific heat of substance B is 1.17 J/g-degrees celsius, what is the specific heat of substance A?
