Answer: The mass percent of nitrogen in the sample is 8.2 % Explanation: Kjeldahl method is defined as the analytical method which is used in the determination of nitrogen content in any organic compound.. Calculate the mass of nitrogen in the sample in grams. In water, most of the ammonia changes to ammonium ions (NH +). Ammoniacal nitrogen (NH 3-N) is a measure for the amount of ammonia, a toxic pollutant often found in landfill leachate and in waste products, such as sewage, liquid manure and other liquid organic waste products. Answer to: A chemist creates 20.4 grams of ammonia in the reaction of 5.50 g hydrogen and excess nitrogen. Performance & security by Cloudflare, Please complete the security check to access. Chemistry The Mole Concept Percent Composition. In this method, nitrogen is converted into ammonia and the ammonia formed is then reacted with an acid. This percentage in decimal form can be multiplied by the total ammonia of the sample to calculate the NH 3 form ammonia. We would need the following equalities to set up conversion factors: 1 mol N2 = 28.014 g … The formula indicates that in each mole of #"NH"_3#, there is one mole of #"N"# atoms.

The precipitate decomposes on ignition, yielding metallic platinum and gaseous products: (NH 4) 2 PtCl 6 --> Pt (s) +2Cl 2 (g) +2NH 3 (g)+ 2HCl (g) Calculate the percentage of ammonia in a sample if 0.2115 g gave rise to 0.4693 g of platinum. Ammonia contains about 82.35 % nitrogen by mass. It can also be used as a measure of the health of water in natural bodies such as rivers or lakes, or in man made water reservoirs. Ammonia easily dissolves in water, and in this form is known as liquid ammonia, aqueous ammonia or ammonia solution. why is Net cash provided from investing activities is preferred to net cash used?
