When 600 mL of 0.2 M HNO₃ is mixed with

400 \mathrm{~mL}

of 0.1 M NaOH solution in a flask, the rise in temperature of the flask is ___________

\times 10^{-2}{ }\,^{\circ} \mathrm{C}

. (Enthalpy of neutralisation

=57 \mathrm{~kJ} \mathrm{~mol}^{-1}

and Specific heat of water

=4.2 \,\mathrm{JK}^{-1} \mathrm{~g}^{-1}

) (Neglect heat capacity of flask)
