![In the ammonia (NH₃) molecule depicted in the figure, three hydrogen (H) atoms form an equilateral triangle, with the center of the triangle at a distance \( d = 9.40 \times 10^{-11} \) m 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 \( L = 10.14 \times 10^{-11} \) m. What are the (a) x and (b) y coordinates of the molecule's center of mass?
- (a) [Input field for the number] Units [Dropdown for units]
- (b) [Input field for the number] Units [Dropdown for units]
**Diagram Explanation:**
The diagram shows a three-dimensional arrangement of atoms in the ammonia molecule:
- **y-axis** is vertical, with the nitrogen (N) atom located along this axis at the apex.
- **x-axis** is horizontal along the base where the hydrogen (H) atoms form an equilateral triangle.
- **H atoms**: Three red spheres represent hydrogen atoms forming the base.
- **N atom**: A teal sphere represents the nitrogen atom at the apex of the pyramid.
- **Distances**:
- \( L \) represents the distance from the nitrogen atom to each hydrogen atom.
- \( d \) represents the distance from the center of the equilateral triangle to each hydrogen atom.
This setup illustrates the geometric orientation of the atoms needed to compute the center of mass.](https://content.bartleby.com/qna-images/question/82e82db8-362b-4865-93d3-f20edd638ab0/a82a8c6f-3b88-411d-963b-4079824577df/c4d4ci_thumbnail.png)
