Question

Three different liquids are mixed together in a calorimeter. The masses of the liquids are m1 = 520 g, m2 = 715 g, m3 = 370 g. The specific heats are: C1 = 280 J/kg°C, C2 = 535 J/kg°C, C3 = 805 J/kg°C. The initial temperatures of the liquids are: T1 = 24.5 °C, T2 = 59.0 °C, T3 = 84.5 °C. What will be the temperature of the mixture in Celsius? (Enter only a number without a unit.)
