More urgent help needed- last one?
1. Lawn fertiliser contains nitrogen. A 1.3g sample of lawn fertiliser was weighed and carefully transferred to a 250ml volumetric flask. The weighing bottle was washed with a little de-ionised water and added to the content, until it reached the calibration line. A 20ml aliquot of this solution was added to a flask containing 20ml of .1M sodium hydroxide solution. 50ml of de-ionised water was than added. The flask was heated until the reaction NH4+ (aq) +OH-(aq) = NH3 (aq) +H20) (l) was complete. The burette was than titrated with .1M hydrochloric acid, using methyl red as indicator. The end point was reached when 44.3ml had been added. Calculated the amount of NH4+ ions in the 1.3g fertiliser sample and the percentage by mass of nitrogen in the fertiliser, assuming all the nitrogen is present as ammonium ions. Can u plz show working, thanks heaps
