For the following problem you should describe in complete sentences the steps you would take to solve the problem and indicate what information you obtain in each step. You do not need to find a numerical answer. You might want to use dimensional analysis to show that your answer has the correct units. Each year in the spring rhododendrons should be fertilized. The recommended fertilizer is described as 10-8-6, which means 10% N, 8% P2O5 and 6% K2O by mass. How many grams of ammonium nitrate (NH4NO3) would you need to produce 1 kg of fertilizer that is 10% N? You do not need to consider the other compounds that are necessary to provide phosphorous and potassium.

The concentration of a NaOH solution was determined in a single experiment by titrating a weighed sample of pure, dried KHP (FW=204.23 g/mol) with the NaOH. The data are as follows: Weighing by difference: Weight KHP + container (initial) = 11.6723 ±0.0001 g Weight KHP + container (final) = 10.8364±0.0001 g Titration: Volume NaOH (initial) = 1.00±0.02 mL Volume NaOH (final) = 29.50±0.02 mLThis NaOH solution was used to analyze tartaric acid in wine. A 50.00±0.02 mL sample of a white dinner wine required 15.30±0.02 mL of the NaOH using phenolphthalein indicator. Calculate the %w/v tartaric acid (and uncertainty) (FW=150.09 g/mol) {pka1=3.17, pKa2=4.91} of the wine.
