In the ammonia (NH3) molecule of Figure 9-39, three hydrogen (H) atoms form an equilateral triangle, with the center of the triangle at distance d = 9.40 ×10-11 m from each hydrogen atom. The nitrogen (N)atom is at the apex of a pyramid, with the three hydrogen atomsforming the base. The nitrogen-to-hydrogen atomic mass ratio is13.9, and the nitrogen-to-hydrogen distance is L = 10.14×10-11 m. What are the(a)x and (b) y coordinates of the molecule's center of mass?
