Atomic Mass Of Silver



  • The relative atomic mass of an element is also known as the relative atomic weight of an element, or, the atomic weight of an element.
    1. Atomic Mass Of Ag
    2. Atomic Mass Of Silver Chloride
  • Relative atomic mass is often abbreviated as r.a.m.
  • The relative atomic mass of an element (its atomic weight) is given in the Periodic Table.
  • The relative atomic mass of an element is the weighted average of the masses of the isotopes in the naturally occurring element relative to the mass of an atom of the carbon-12 isotope which is taken to be exactly 12.

    • Problem: Calculate the atomic mass of silver if silver has 2 naturally occurring isotopes with the following masses and natural abundances: Ag-107 106.90509 amu 51.84% Ag-109 108.90476 amu 48.46% A) 108.19 amu B) 107.90 amu C) 108.32 amu D) 108.00 amu E) 107.79 amu. Relative Atomic Mass of Silver The formula for relative atomic mass is the relative abundance over 100 divided by the isotope number. This can be expressed as: (A/100. a) + (B/100. b) + (C/100. c). = relative atomic mass.

    The atomic mass unit (u) is defined as a mass equivalent to Atomic mass of silver chloride

    Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article. ››More information on molar mass and molecular weight. 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.

    1/12 of the mass of one atom of carbon-12.

    1 u = 1.66 × 10-27 kg

    We can estmate the the relative atomic mass (atomic weight) of an element E with the naturally occurring isotopes aE, bE, cMassE, etc, and with the respective abundances of A%, B%, C% etc,
    relative atomic mass (r.a.m.) = ( A
    100     		× a) + ( B
    100     		× b) + ( C
    100     		× c) + etc
    Silver 107 mass number Given the relative atomic mass (r.a.m.) of an element and the estimated mass of each of its isotopes, we can then estimate the relative abundance of each isotope: let x = %abundance of isotope-a
    and 100 - x = %abundance of isotope-b
    then, let r.a.m = relative atomic mass of the element:
    r.a.m. = ( x
    100     		× mass isotope-a) + ( 100 - x
    100     		× mass isotope-b)

    and solve for x

    Chloride
  • Note that we can measure the mass of each isotope and its abundance using Mass Spectroscopy

    Computing molar mass (molar weight)

    To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use:
    • Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
    • Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
    • parantesis () or brackets [].
    • Common compound names.
    Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.
    Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.

    Computing molecular weight (molecular mass)

    To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.
    Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.
