2. (2-step problem) How many grams of MnSO4 are produced from 15.8 moles of H2SO4? Again, write out the equation and MAP it for this problem before attempting to solve---it’s a different map, with two steps! 5 KNO2 + 2 KMnO4 + 3 H2SO4  5 KNO3 + 2 MnSO4 + K2SO4 + 3H2O

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.

Calculate the percent composition by mass of each element in al(oh)3. use at least three significant figures.

How many grams of phosphorus are contained in 5.09 moles of phosphorus?
