When two moles of liquid A are mixed with two moles of liquid B at 300 K , the excess molar Gibbs energy of the solution is $-1.5 \mathrm{kJ} \mathrm{mol}^{-1}$. The corresponding value of Gibbs energy of mixing (in kJ) is closest to $\left(\mathrm{R}=8.3 \mathrm{J} \mathrm{K}^{-1} \mathrm{mol}^{-1}\right)$
