Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calculated whose chemical formula is given.
Chemical Properties of Hydrogen Gas – H 2. Hydrogen involves in the production of methanol. In the synthesis, reaction hydrogen is not separated from the synthesis gas stream. The reaction is given below. CO + 2H2 → CH3OH. Atmospheric nitrogen combined with hydrogen results in the production of ammonia. N2 + 3H2 → 2NH3.
A gram molecule of Hydrogen. A gram molecule is the number of molecules present in one mole of that substance, instead of the atoms. Weight of one mole of Hydrogen= 1. 008 g; Weight of 6. 022 × 10 23 atoms of Hydrogen= 1. 008 g; As, 6. 022 × 10 23 atoms of Hydrogen weighs 1. 008 g. 1 atom of Hydrogen weighs= 1 6. 022 × 10 23 = 1. 66058 × 10 ...

Given molecular weight of hydrogen molecule is M =2.016 × 10 3 kg / mol. Calculate the root mean square speed of hydrogen molecules H 2 in km / s at 373.15 K 100∘ C .
Sodium dihydrogen phosphate reacts with bases like sodium hydroxide resulting in the formation of sodium hydrogen phosphate and water. NaH2PO4 + NaOH → Na2HPO4 + H2O. Sodium dihydrogen phosphate reacts with acid like hydrochloric acid results in the formation of phosphoric acid and sodium chloride. NaH2PO4 + HCl → H3PO4 + NaCl.
Hydrogen Sulfate is an anion with the chemical formula HSO4–. It forms sulfuric acid when exposed to water. HSO 4– very small hydrogen sulfate ion. Sodium Bisulfate which is the pure substance NaHS0 4 melts at 185°C and begins to lose water with a good deal of spattering. It consists of sulfur atom in the center surrounded by four oxygen ...
