Enthalpy dH = q = mCpdT
with,
m = 44 g
Cp = 4.184 J/g.oC
dT = 30.17 - 23.50 = 6.67 oC
we get,
dH = 44 x 4.184 x 6.67 = 1.228 kJ
dH per mole of H2SO4,
dH = 1.228/0.5 M x 0.022 ml = 111.636 kJ/mol

You should use care when dissolving H_2SO_4 in water because the process is highly exothermic. To measure the enthalpy change, 4.5 g of concentrated H_2SO_4 (l) was added (with stirring) to 148 g of water in a coffee-cup calorimeter. This resulted in an increase in temperature from 20.8 degree C to 27.7 degree C. Calculate the enthalpy change for the process H_2SO_4 (l) rightarrow H_2SO_4(aq), in kJ/mol. Assume the specific heat capacity of the solution is 4.2 J/g K. Enthalpy...
