5.A coffee cup calorimeter having a heat capacity of 451 J/oC was used to measure the heat evolved when 0.0300 mol of NaOH(s) was added to 1000 mL of 0.0300 M HNO initially at 23.000 oC. The temperature of the water rose to 23.639 oC. Calculate H (in kJ/mol NaNO3) for this reaction. Assume the specific heat of the final solution is 4.18 J/goC; the density of each solution is 1.00 g/mL; and the addition of solid does not appreciably affect the volume of the solution. HNO3(aq) NaOH(s) NaNO3{aq) H20() (a)-63.7 kJ/mol (b)-151 kJ/mol (c)-2.55 kJ/mol (d)-81.4 kJ/mol (e)-98.6 kJ/m
