Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?
