Question
How much milk at 10.00°C needs to be added to a small 150.0 ml cup of coffee at 95.00 °C to drop the temperature to 90.00°C?
Assume coffee and milk have the same specific heat capacity as water: 4.186 J/g °C or 1 cal/ g °C, and they also have the same density: 1.0 g/mL

[mass milk x specific heat milk x (Tfinal-Tinitial)] + [mass coffee x specific heat coffee x (Tfinal-Tinitial)] = 0
Substitute and solve for mass milk.
