Identify the correct statements : A. The molality of $\displaystyle 2.5 \mathrm{~g}$ of ethanoic acid (Molar mass : $\displaystyle 60 \mathrm{~g} \mathrm{~mol}^{-1}$ ) in $\displaystyle 75$ g of benzene solution is $\displaystyle 0.556$ m. B. The molarity of a solution containing $\displaystyle 5$ g of NaOH (molar mass : $\displaystyle 40 \mathrm{~g} \mathrm{~mol}^{-1}$ ) in $\displaystyle 450$ mL of solution is $\displaystyle 0.278$ M at $\displaystyle 298$ K. C. Aquatic species are more comfortable in cold water. D. The solubility of gas increases with decrease in pressure. E. For a binary mixture of A and B, the number of moles of A and B are $\displaystyle \mathrm{n}_{\mathrm{A}}$ and $\displaystyle \mathrm{n}_{\mathrm{B}}$ respectively. The mole fraction of B will be $\displaystyle \mathrm{x}_{\mathrm{B}}=\frac{\mathrm{n}_{\mathrm{A}}}{\mathrm{n}_{\mathrm{A}}+\mathrm{n}_{\mathrm{B}}}$. Choose the correct answer from the options given below :
