Question

A 0.60 L portion of a 1.2 M AgNO3 solution is mixed with a 0.3 L potion of a 1.2 M Na2CrO4 solution in an constant pressure calorimeter. Upon mixing, the solid Ag2CrO4 is formed and the heart released is 48.2 kJ. The specific heat of the solution is 4.18 J/C*g and the final density is 1.009 g/ml. What is the temperature change of the solution?

Answer 1

48,200 = mass x specific heat x delta T.
mass = 900 mL x 1.009 g/mL
Solve for delta T.
