A chemistry student needs of acetone for an experiment. He has available of a w/w solution of acetone in chloroform. Calculate the mass of solution the student should use. If there's not enough solution, press the "No solution" button. Be sure your answer has the correct number of significant digits.

How have the competing explanations' experiments on atoms affected the development of the atomic model?

Examples of states of consciousness include a. daydreaming b. dreaming during sleep c. hypnosis d. all of the above

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
