When a 5.00g sample of KBr is dissolved in water in a calorimeter that has a total heat capacity of 3.982 kJ-K, the temperature decreases by .210 K. Calculate the molar heat of solution of KBr.

=____kJ/mol

4 answers

q in kJ = Ccal x delta T
dH/g= q/5
dH/mol = (q/5) x (molar mass KBr/mol) = ?
I have no idea!
I'm so confused
I gave you directions. Follow the directions.
Ccal = 3.982 kJ/K and delta T = 0.95.
q = Ccal x 0.95
That gives you q in kJ and
(q/5) x molar mass KBr = q in kJ/mol.
