200 mL of 0.2 M HCl is mixed with 300 mL of 0.1 M NaOH. The molar heat of neutralization of this reaction is −57.1 kJ. The increase in temperature in oC of the system on mixing is x × 10⁻² The value of x is (Nearest integer) [Given: Specific heat of water = 4.18 J g⁻¹ K⁻¹ Density of water = 1.00 g cm⁻³]
