A 10.0 lb bag of 20:10:5 fertilizer is 20.0% nitrogen by weight.
a) Calculate how many grams of nitrogen are contained in the bag. (I got 907 grams of Nitrogen)
b) If the bag of fertilizer covers 8.6 x 10^4 ft^2, calculate the number of grams of nitrogen per square foot of coverage.
If a weak acid solution, HA is 0.3M and ionizes 1%, what will be the concentrations of [HA], [H3O+],and [A-] at equilibrium
The flask was then shaken until the solution was uniform. A 25.0-mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100. mL of the final solution?
A saturated aqueous solution of lead(II) iodate, Pb(IO3)2, contains 3.1 x 10-5 M Pb+2 at 25°C. Assuming an ideal solution, and assuming no reaction of the ions with water, calculate the Ksp of lead(II) iodate at that temperature.
In an electrolytic cell, Cu(s) is produced by the electrolysis of CuSO4(aq). Calculate the maximum mass of Cu(s) that can be deposited by a direct current of 100. amperes passed through 5.00 L of 2.00 M CuSO4(aq) for a period of 1.00 hour.
For the subsequent reactions, State the balanced formula equation, complete ionic equation and net ionic equation. If no precipitate forms, write No reaction.
We use standard addition methods when our sample has matrix effects which are hard to duplicate in a blank. Let's again find the amount of Pb+2 in a blood sample. A 5.00 mL blood sample containing lead yielded a signal of 0.712 units.
Calculate the molarity and mole fraction of acetone in a 1.26 m solution of acetone (CH3COCH3) in ethanol (C2H5OH). (Density of acetone = 0.788 g/cm3; density of ethanol = 0.789 g/cm3.) Assume that the volumes of acetone and ethanol add.
