When a 4.00g sample of KBr is dissolved in water in a calorimeter that has a total heat capacity of 2.908 kJ x K^-1, the temperature decreases by .230 K. Calculate the molar heat of KBR

  • General Chemistry (College LvL) -

    moles KBr = 4.00/molar mass = ??
    2.908 kJ/K x 0.230 K = ?kJ.
    Then molar heat of KBr = ?kJ/?mole.
