Calculate the Molecular mass of phosphorus pentoxide : P2O5. Solution step by step<\/p>\n\n\n\n
The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n To calculate the molecular mass of phosphorus pentoxide (P\u2082O\u2085)<\/strong>, we follow these step-by-step instructions<\/strong>:<\/p>\n\n\n\n Step 1: Identify the elements and number of atoms in the compound P\u2082O\u2085<\/strong><\/p>\n\n\n\n Step 2: Use the atomic masses from the periodic table<\/strong><\/p>\n\n\n\n Step 3: Multiply the atomic mass by the number of atoms for each element<\/strong><\/p>\n\n\n\n Step 4: Add the total masses together to get the molecular mass<\/strong><\/p>\n\n\n\n 141.94 g\/mol<\/strong><\/p>\n\n\n\n Molecular mass (or molecular weight) is the sum of the atomic masses of all the atoms in a molecule. It is expressed in grams per mole (g\/mol) and helps us understand how much one mole of a compound weighs.<\/p>\n\n\n\n In this case, phosphorus pentoxide has the chemical formula P\u2082O\u2085, meaning it consists of 2 phosphorus atoms<\/strong> and 5 oxygen atoms<\/strong> bonded together in one molecule.<\/p>\n\n\n\n Using the periodic table<\/strong>, we find the atomic mass of phosphorus is approximately 30.97 g\/mol, and oxygen is 16.00 g\/mol. These values represent the average mass of an atom of each element, considering all naturally occurring isotopes.<\/p>\n\n\n\n To find the molecular mass:<\/p>\n\n\n\n Adding these two results gives: This value tells us that one mole of phosphorus pentoxide molecules weighs 141.94 grams. This information is essential in chemical reactions<\/strong>, where accurate amounts of substances are needed for stoichiometry \u2014 the calculation of reactants and products in chemical equations.<\/p>\n\n\n\n Thus, knowing the molecular mass of P\u2082O\u2085 helps chemists determine how much of it to use or expect in reactions involving phosphorus and oxygen.<\/p>\n","protected":false},"excerpt":{"rendered":" Calculate the Molecular mass of phosphorus pentoxide : P2O5.
