Where is the fulcrum of this lever? Circle and label its location on the diagram above.

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.

For ai it's atomic number is 13 and it's mass number is 27 how many neutrons does it have
