Question
The specific heat of compound AB(s) was determined using coffee-cup calorimeter. When
1.750 g of AB(s) was mixed with 15.00 mL deionized distilled water at room temperature, only 0.850
grams of the compound was dissolved. The temperature of the heterogenous mixture was decreased
by 1.70K.
Prior to this, the calorimeter was calibrated using a 15mL aqueous reaction mixture that initially
contains 0.070 moles each of HBr and KOH. The recorded ΔT is +5.75K.
Note:
H+(aq) + OH -(aq) → H2O(l) ΔH = -55.85 kJ/mol
AB(s) ⇌ A+(aq) + B-(aq) ΔH = 88.75 kJ/mol
specific heat (H2O) = 4.184 J/g°C
MM of AB = 65 g/mol
What is the specific heat of solid AB compound (in J/g°C)?
