Determine the size of the heavy particle using the simulation tools and then relate molecule size to something you are familiar with. A common way to relate two things is to say something like: 1000 particles of sand fit in the palm of your hand. Show your calculations with the units clearly labeled.

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.
