A common organic solvent used in the laboratory vaporizes readily. If the pressure of the compound's vapor in a flask is 193 mmHg at 25 °C, and the density of the vapor is 0.426 g/L, what is the molar mass of the compound?

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.
