Isentropic compressibility (s), intermolecular free length (Lf), apparent molar volume (v), apparent molar compressibility (k), molar compressibility (W), molar sound velocity (R), and acoustic impedance (Z) of Ni are among the acoustic properties studied (NO3). The ultrasonic velocity (U), density (), and relative viscosity (r) of 6H2O in 10%,...
