the centre of the pyramid in the nh3 molecule is at a distance of 9.40 from each hydrogen atom...nitrogen to hydrogen mass ratio is 13.9 and nitro to hydro distance is 10.14....find the centre of mass of the system with respect to the nitrogen atom....

Dear Shivanshi,

 I can suggest u a method to solve this problem. Consider the nitrogen molecule as a origin and we know the angles of the pyramid for the ammonia molecule and also they provided data related to the distance of the centre of the pyramid which is the centroid of the tetrahedron and using these data and geometric relations for 3 D geometry we cansolve this problem.
