Question
When pure sulfuric acid is dissolved
in water, heat is evolved. 10.65 g of
pure sulfuric acid at 20.00 °C was
added to a calorimeter containing
300 g of water at 20.00 °C. The
temperature of the solution
increased to 26.35 °C. If the specific
heat of the mixture is 4.184 Jg1°C1,
the density of water is 1 g/mL, and
the heat capacity of the calorimeter
is ignored, what is the heat evolved
per mole of sulfuric acid?
a. -83.2 kJ
O b. -73.6 kJ
O C. -76.0 kJ
d. -80.8 kJ
e. -78.4 kJ
