Explanation:The amount of heat required to change the temperature of a substance is given by the equation:Q = m * c * ΔTwhere:Q is the heat energy in joulesm is the mass of the substance in gramsc is the specific heat of the substance in J/g⋅°CΔT is the change in temperature in °CIn this problem, we have:m = 8.50 gc = 0.902 J/g⋅°CΔT = 93.4°C - 25.0°C = 68.4°CPlugging these values into the equation, we get:Q = 8.50 g * 0.902 J/g⋅°C * 68.4°C = 524 JTherefore, the correct answer is E) 524 J.
