phosphorus mass number

Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. phosphorus' atomic mass,it's weight,is 30.974 the atomic number on the other hand is 15 This site explains how to find molar mass. Bemerkungen: 1 Digit = niederwertigste Stelle, d.h. 2,435 +/- 3 Digits bedeutet 2,432 … 2,438; Die »CAS Registry Number« ist die dem Element Phosphor vom Chemical Abstracts Service zugewiesene Schlüsselnummer, die das Auffinden von Fachartikeln über dieses Element in allen nach dem CAS-System strukturierten Publikationen und Datenbeständen erleichtert. at 0℃ and one atmosphere pressure. 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. Deborah. Lv 4. Melting point of Phosphorus is 44 (P4) °C and its the boiling point is 280 (P4) °C. Melting point of Phosphorus in Kelvin is 317.3 K. Abundant value of Phosphorus is 1050 mg/kg.

Phosphorus is a chemical element which comes in two forms, red and white one. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Lv 7. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. 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. ›› More information on molar mass and molecular weight. Atomic weight of Phosphorus is 30.973762 u or g/mol. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. A common request on this site is to convert grams to moles. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. It depends on the isotopes. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. In nature, phosphorus can be found as an element of various compounds like phosphate rocks and other minerals. Enter a chemical formula: Browse the list of common chemical compounds. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. Number of protons = 15. We use the most common isotopes. Mass number = 31 = number of protons + number of neutrons. To complete this calculation, you have to know what substance you are trying to convert. Chemical symbol for Phosphorus is P. Number of protons in Phosphorus is 15. Melting point of Phosphorus is 44 (P4) °C and its the boiling point is 280 (P4) °C.
