4. You mix 50.0 ml. of a weak monoprotic acid with 50.0 mL of NaOH solution in a coffee cup calorimeter. Both solutions and the calorimeter were initially at 23.9°C. The final temperature of the neutralization reaction was determined to be 41.2°C. The calorimeter constant was known to be 110.6J/°C. Density Aqueous Solution = 1.00 g/ml Specific Heat of water = 4.184 J/g °C Hide a. What is the total amount of heat evolved in this reaction? NG 3 b....

4. Heat transfer: q = mass x Cs x ΔT and –qreaction = +qsolution a. A piece of metal with a mass of 8.6 g was heated to 100.0°C and dropped into a coffee cup calorimeter containing 402.4 g of water at 25.0°C. If the temperature of the water and the metal at thermal equilibrium is 26.4°C, what is the specific heat of this metal in J/g°C? b. How much heat energy must be added in order to boil a...

We did the lab of latent heat of fusion of ice, and I am
confused that what the 'water equivalent' represents.
I thought it is the amount (kg) of water, but it is
mccc according to this lab manual, which unit
is (J/oC).
Please answer what the water equivalent represents and the unit
of it.
