Molar Mass Chlorine



  • Gravimetric analysis is the quantitative isolation of a substance by precipitation and weighing of the precipitate.1
  • Use this periodic table for calculating molar mass for any chemical formula. Options for hiding the symbol or name of the elements provide a handy learning aid for memorizing the periodic table. IOS app is also available. My Work: SInce mass = number of mols x Molar mass, I first look for the molar mass of Ag2CO3, which is 275.75 g/mol. Chemistry 3.13 g of sodium (Na) react with 7.17 g of chlorine (Cl2) to produce 10.3 g of sodium chloride (NaCl). The molar mass is 35.5 g (according to the periodic table) The molar mass is generally the mass of one mole of that substance (chlorine). One mole of chlorine equals to 6.02214×10^23 atoms of chlorine. Be careful not to confuse molar mass with molecular mass, though. Molecular mass of chlorine would be mass of ONE chlorine atom. The average molar mass of chlorine is 35.5 g mol –1. The ratio of 35 Cl to 37 Cl in naturally occurring chlorine is close to: (1) 4: 1 (2) 1: 1 (3) 2: 1 (4) 3: 1. ›› Chlorine Pentafluoride molecular weight. Molar mass of ClF5 = 130.445016 g/mol. Convert grams Chlorine Pentafluoride to moles or moles Chlorine Pentafluoride to grams. Molecular weight calculation: 35.453 +.5 ›› Percent composition by element.

  • Seawater contains dissolved chloride ions, Cl-(aq).2
  • Molar Mass Chlorine
  • Gravimetric analysis can be used to determine the amount of chloride present in seawater by precipitation of the chloride as insoluble silver chloride 3, AgCl
    Ag+(aq) + Cl-(aq) → AgCl(s)
  • The mass of silver chloride precipitated is used to calculate:

    (i) moles of AgCl(s) precipitated
    moles = mass ÷ molar mass

    (ii) moles of chloride ion, Cl-, present
    mole ratio AgCl:Cl- is 1:1

    (iii) mass of chloride ion, Cl-, present in the seawater.
    mass = moles × molar mass

    The amount of chloride dissolved in the seawater, the concentration of chloride ion in seawater, is usually expressed in units of the mass of chloride per volume of seawater: (i) grams of chloride in 100 mL of seawater: g/100 mL
    Molar Mass Chlorine(that is, a percentage, w/v%)

    (ii) grams of chloride per litre of seawater: g L-1


    The concentration of chloride ions in seawater can also be given as a concentration in moles per litre:
