0Ethanol has a density of \( 659 \mathrm{~kg} / \mathrm{m}^{3} \). If the speed of sound in ethanol is \( 1162 \mathrm{~m} / \mathrm{s} \), what is its adiabatic bulk modulus?
(A) \( 1.7 \times 10^{8} \mathrm{~N} / \mathrm{m}^{2} \)
(B) \( 7.7 \times 10^{8} \mathrm{~N} / \mathrm{m}^{2} \)
(C) \( 2.2 \times 10^{8} \mathrm{~N} / \mathrm{m}^{2} \)
(D) \( 8.9 \times 10^{8} \mathrm{~N} / \mathrm{m}^{2} \)
