So, the average atomic mass of chlorine = 35.4527 u . The isotope chlorine-35 has a mass of 34.96885 atomic mass units, and the isotope chlorine-37 has a mass of 36.96590 atomic mass units. ››More information on molar mass and molecular weight. Both Chlorine isotopes, Cl-35 and Cl-37, are used to study the toxicity of environmental pollutant and are usually supplied in the form of NaCl. Naturally occurring isotopes This table shows information about naturally occuring isotopes , their atomic masses , their natural abundances , their nuclear spins , and their magnetic moments . The SI base unit for amount of substance is the mole. The atomic weight of chlorine given on the periodic table is 35.47 u. Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, … In other words, in every 100 chlorine atoms, 75 atoms have a mass number of 35, and 25 atoms have a mass number of 37. Relative atomic mass The mass of an atom relative to that of carbon-12. Density is the mass of a substance that would fill 1 cm 3 at room temperature. Previous Question Next Question. Given the information that 75.7771% of … Atomic mass of Chlorine is 35.453 u. Following its 1967 discussion of Ag, Cl, and Br, which were important in the chemical determination Chlorine -35 is about 3 times more abundant than chlorine – 37, the weighted average is closer to 35 than 37. About three quarters of all chlorine atoms have 18 neutrons, giving those atoms a mass number of 35. Where more than one isotope exists, the value given is the abundance weighted average. 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. Q:-Calculate the amount of carbon dioxide that could be produced when (i) 1 mole of carbon is burnt in air. Chlorine In 1961, the Commission recommended Ar(Cl) = 35.453(1), based on the atomic weight of silver and on Ag/AgCl equivalent ratios determined chemically by many well-known authorities. Chlorine (atomic number 17) is a yellowish-green toxic gas. This is approximately the sum of the number of protons and neutrons in the nucleus. Note that rounding errors may occur, so always check … The molecular formula for Chlorine is Cl. About one quarter of all chlorine atoms have 20 neutrons, giving those atoms a mass number of 37. The atomic mass is the mass of an atom. The average atomic mass of the given sample of chlorine is 35.46 u. Isotopes Different isotopes have different relative abundances,chlorine – 35 has a relative abundance of 75.76%,whereas chlorine – 37 has a relative abundance of 24.24%. Popular Questions of Class Chemistry. Chlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.
