Assuming that the density of vinegar is 1.005 g/ml, calculate the molatrity of acetic acid in vinegar from an average of 4.6% for the mass percentage of acetic acid in vinegar.

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.
