3) A company needs to verify the amount of nitrogen in their new "QuikGreen" fertilizer product. To test the nitrogen content, a 5.01 g sample of fertilizer is dissolved in 100.0 mL of water, and powdered aluminum and sodium hydroxide are added. The mixture is left to react and then heated to remove any dissolved NH3, which is transferred to a flask containing 50.0 mL of 0.989 M hydrochloric acid where it undergoes a neutralization reaction. The HCI solution is then titrated to a methyl red endpoint using 11.74 mL of 0.251 M sodium hydroxide. a) How many grams of nitrate were in the original sample? b) The first N-P-K fertilizer number represents percent nitrogen. Based on your answer, what is the percent nitrogen in the tested fertilizer sample?
