A sound wave in air has a pressure amplitude equal to 4.04 ✕ 10-3 Pa. Calculate the displacement amplitude of the wave at a frequency of 9.4 kHz. (Note: Use the following values, as needed. The equilibrium density of air is ρ = 1.20 kg/m3; the speed of sound in air is v = 343 m/s. Pressure variations ΔP are measured relative to atmospheric pressure, 1.013 105 Pa.)

At a certain temperature the vapor pressure of pure thiophene (CH S) is measured to be 0.39 atm. Suppose a solution is prepared by mixing 71.5 g of thiophene and 68.6 g of heptane (CGH16) Calculate the partial pressure of thiophene vapor above this solution. Round your answer to 2 significant digits. Note for advanced students: you may assume the solution is ideal.
