Determine the number of moles of cr atoms in 50.00grams of cr2cl3

molar mass of cr2cl3 = 158.5 g/mole
number of mole of cr2cl3 in 50 grams of cr2cl3= 0.3155 moles

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.
