In the ammonia (NH3) molecule, three hydrogen (H) atoms form an equilateral triangle, with the center of the triangle at distance d = 94.0 pm (picometer) from each hydrogen atom. The nitrogen (N) atom is at the apex of a pyramid, with the three hydrogen atoms forming the base. The nitrogen-to-hydrogen atomic mass ratio is 13.9, and the nitrogen-to-hydrogen distance is L = 101.4pm. What are the (a)x and (b)y coordinates of the molecule's center of mass?  [Answer: (a) 0; (b)31.3 pm]. SHOW work, work needs to be shown
