If 0.10 mol of ammonium chloride (NH4Cl) is dissolved in water producing 2.27 x 102
g solution, the water temperature decreases from 25.0°C to 19.0°C. Given
that the specific heat of the resulting solution is 1.00 cal/g.°C), calculate the
energy absorbed by the system?
A. 4.18)
B. 5.9 x 10^3 cal
C. 1.4 x 10^3 cal
D. 1.00 cal
E. 0.10 cal
