Calculate the molar mass and percent nitrogen in the different fertilizers. In 100 g of NH 4 NO 3, mass of nitrogen is = 28×100/80 = 35%. Switch; Flag; Bookmark; 23. Ammonium nitrate, a salt of ammonia and nitric acid, used widely in fertilizers and explosives. Varieties of LPG are marketed including a mixture of propane (60%) and butane (40%). So percentage of nitrogen in ammonium nitrate … Copper(II) fluoride contains 37.42% F by mass. [Relative molecular mass of ammonium nitrate is 80, H = 1, N = 14, O = 16]. What is the mass of one mole of the compound? (a) What fraction of the neutron's kinetic energy is transferred to the . Copper used in electric wires comes in two flavors (isotopes): 63Cu and 65Cu. Combustion, 2C2H10(g) +13O2(g) -------> 8CO2(g) +10H2O (g). Calculate the percentage of nitrogen and oxygen in ammonium nitrate. Mass of nitrogen in 1 mole of NH 4 NO 3 =2 x 14 = 28 g. Mass of oxygen in 1 mole of NH 4 NO 3 = 16 x 3 = 48 g. Mass of 1 mole of NH 4 NO 4 = 80 g. Percentage of nitrogen in NH 4 NO 3 = 28/80 x 100 = 35% chemistry. (ii) What is the common property demonstrated by this experiment? Get the answers you need, now! A bag of fertilizer contains 500g of ammonium sulfate, $ \small \ce{(NH4)2 SO4}$, and 500g of potassium nitrate, $\small \ce{KNO3}$. Electrolytic cell B contains an acetic acid solution and in this case, the bulb in the circuit glows dimly. Determine the percentage of oxygen in ammonium nitrate. 15. STATE WHICH OF THE FOLLOWING ARE BETTER FERTILIZERS- 1.POTTASIUM PHOSPHATE OR POTASSIUM NITRATE 2.UREA AMMONIUM PHOSPHATE. So in 80 g of NH 4 NO 3, mass of nitrogen is = 14 +14 = 28g. Write the equation for each of the following reaction; zinc oxide is treated with sodium hydroxide solution. Calculating percentage by mass. Practice to excel and get familiar with the paper pattern and the type of questions. The gram formula mass of ammonium nitrate is 80.04 and the gram atomic mass of nitrogen is 14.0067. 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. 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. [K=39,P=31,O=16,N=14,H=1].
