Question

Three different liquids are mixed together in a calorimeter. The masses of the liquids are:
m₁ = 590 g,
m₂ = 830 g,
m₃ = 445 g.
The specific heats are:
c₁ = 285 J/kg°C,
c₂ = 575 J/kg°C,
c₃ = 840 J/kg°C.
The initial temperatures of the liquids are:
T₁ = 29.0 °C,
T₂ = 55.5 °C,
T₃ = 83.0 °C.
What will be the temperature of the mixture in Celsius? (Enter only a number without a unit.)
