Before placing in Container D, check the pH with pH-Universal indicator strips (Item No. Counting the number of atoms of each element in the compound. Neutral solutions of the these salts: Container D. Finding the atomic masses of elements in the periodic table. P337 + P313: If eye irritation persists: Get medical advice/ attention.ĥ.1C Ammonium nitrate and ammonium nitrate containing preparationsġ4 Inorganic salts: Container I. Periodic Table Periodic Trends Element Charts Future Elements. Ammonium has a chemical formula NH4+ and nitrate has the chemical formula NO3. The molecule of ammonium nitrate is formed by the union of 2 nitrogen atoms, 4 hydrogen atoms and 3 oxygen atoms. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in Pb (No3)2: Molar Mass (g/mol) Pb (Lead) 1 × 207.2 207.2. Remove contact lenses, if present and easy to do. The molar mass and molecular weight of O3H4N2 (Ammonium Nitrate) is 80.043. Ammonium nitrate is a chemical compound that is made up when an ammonium ion unites with a nitrate ion. P305 + P351 + P338: IF IN EYES: Rinse cautiously with water for several minutes. P280: Wear protective gloves/ protective clothing/ eye protection/ face protection/ hearing protection. P264: Wash skin thoroughly after handling. P220: Keep away from clothing and other combustible materials. P210: Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. The concept of molar mass can also be applied to compounds. P210: Keep away from heat/sparks/open flames/hot surfaces.
