Various acoustical properties such as isentropic compressibility (ks), Rao’s molar sound function (Rm), the Van der Waals constant (b), molar compressibility (W), inter molecular free length (Lf), relaxation strength (r), internal pressure (p), solvation number (Sn) etc., were calculated. The results are interpreted in terms of molecular interaction occurring in the solutions.   UR - https://ijcce.ac.ir/article_7134.html L1 - https://ijcce.ac.ir/article_7134_04a7641fa9c58c37f615a68cb22e3799.pdf ER -
