Calculation of percentage of nitrogen. Most forms of organic nitrogen cannot be taken up by plants, with the exception of some small organic molecules. Excessive nitrogen deposition can lead to significant biodiversity loss through loss of plant species and changes in … Classically, this method is used to estimate the protein content of food and the amount of nitrogen in soil samples. If the answer is not available please wait for a while and a community member will probably answer this 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. The commercial grade contains about 33.5 percent nitrogen, all of which is in forms utilizable by plants; it is the most common nitrogenous component of artificial fertilizers. However, mineral nitrogen in soil accounts for only 2 % of the nitrogen in soil. Video-Given atomic masses and chemical formulas, find the mass % [mass percentage] What is the mass percentage of nitrogen in ammonia? Calculating the mass of 1 molecule of ammonia: Mass = ( Number of hydrogen atoms x Mass of hydrogen atom) + ( Number of nitrogen atoms x Mass of nitrogen atoms) Mass = ( 3 x 1 ) + ( 1 x 14) = 17.
