Use the experimental values to calculate the enthalpy change
Quantity of reactant 1: 5.61 g KOH(s)
Quantity of reactant 2: 200.0 mL of 0.50 M HBr(aq)
Initial Temperature (oC): 20.0
Final Temperature (oC): 26.7
Can someone please tell me the next step?
So far, I have:
ΔT = tf – ti
= 26.7 oC - 20.0 oC
= 6.7 oC
