Lv 7. molar mass and molecular weight. In nature, phosphorus can be found as an element of various compounds like phosphate rocks and other minerals. 0 0. maussy. The person who answered before me has given the mass of the stable isotope P31. Phosphorus is a chemical element which comes in two forms, red and white one. Atomic weight of Phosphorus is 30.973762 u or g/mol. State of Phosphorus is Solid at standard temperature and pressure We use the most common isotopes. ›› More information on molar mass and molecular weight. It depends on the isotopes. 5 … Mass Percent: Phosphorus: P: 30.973761: 1: 100.000% ›› Calculate the molecular weight of a chemical compound. Boiling point of Phosphorus in Kelvin is 550 K. Phosphorus melting point is 44 (P4) °C. 0 0. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. Melting point of Phosphorus is 44 (P4) °C and its the boiling point is 280 (P4) °C. » Boiling Point » Melting Point » Abundant » State at STP » Discovery Year About Phosphorus . of a chemical compound, More information on Atomic number = 15 = number of electron = number of protons. Browse the list of This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. Für nähere Informationen zur Nutzung Ihrer Daten lesen Sie bitte unsere Datenschutzerklärung und Cookie-Richtlinie. Phosphorus is a chemical element which comes in two forms, red and white one. Chemical symbol for Phosphorus is P. Number of protons in Phosphorus is 15. Dazu gehört der Widerspruch gegen die Verarbeitung Ihrer Daten durch Partner für deren berechtigte Interessen. Industrially, phosphorus and its compounds can be used as fertilizers, steel production, producing detergents, household goods, soft drinks, poison for rodents, and so on. Chemical symbol for Phosphorus is P. Number of protons in Phosphorus is 15. Deborah. Phosphorus boiling point is 280 (P4) °C. This element is crucial for all living things on our planet since it supports energy generating processes. Source(s): mass number phosphorus: https://biturl.im/wbC6c. common chemical compounds. Enter a chemical formula: Browse the list of common chemical compounds. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. This chemical element has got its name after the Greek expression meaning brighter than light since this element glows in the dark by slow ‘burning’ light. Exposure to white phosphorus should not exceed 0.1 mg/m 3 (8-hour time-weighted average per 40-hour work week). Phosphorus. Lv 4. Phosphorus is very poisonous, 50 mg constituting an approximate fatal dose. Calculate the molecular weight The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. White phosphorus should be kept under water (as it is dangerously reactive in air) and should be handled with forceps, as contact with the skin may cause severe burns. Mass number = 31 = number of protons + number of neutrons. Iwould rather say its mass number is 31 beiin g made of 15 protons and 16 neutrons. Melting point of Phosphorus in Kelvin is 317.3 K. Abundant value of Phosphorus is 1050 mg/kg. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. at 0℃ and one atmosphere pressure.

Dies geschieht in Ihren Datenschutzeinstellungen. Sign in. Number of protons = 15. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Sie können Ihre Einstellungen jederzeit ändern. Number of neutrons = 31-15 = 16 In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
