A student determined the calorimeter constant of the calorimeter. The student added 50.00 mL of cold water to 50.00 mK of heated , distilled water in a styrofoam cup. The initial temp of the cold water was 21,00C and the hot water, 29.15C. The maximum temp pf the mixture was found to be 24.81C. Assume the density of water is 1.00g mL-1 and the specific heats is 4.184 J g-1 K-1

Question

A student determined the calorimeter constant of the calorimeter. The student added 50.00 mL of cold water to 50.00 mK of heated , distilled water in a styrofoam cup. The initial temp of the cold water was 21,00C and the hot water, 29.15C. The maximum temp pf the mixture was found to be 24.81C. Assume the density of water is 1.00g mL-1 and the specific heats is 4.184 J g-1 K-1 
It's asking me to find the heat lost by hot water

DrBob222 · Answer

heat lost by hot water q = mass hot water x specific heat H2O x (Tfinal-Tinitial)
