35.453
-------------
The relative atomic weight (not mass) of chlorine is after IUPAC tables from 2009 [35,446; 35,457]; the conventional value is 35,45.

Chlorine (Cl), atomic number 17.
No. chlorine has an atomic weight 0f 35.45. and has an atomic number (number of pprotons) of 17. It has two naturally occuring isotopes chlorine-35 and chlorine -37. It is the presence of these that causes the fractional atomic weight
Atomic weight of hydrogen is 1,008. Atomic weight of carbon is 12,011. Atomic weight of chlorine is 35,45. The sum is the molar mass of CHCl3: 119,369 g.
They use a number called a mole. This many atoms of an element equals its atomic weight in the periodic table. Molecular weight is the sum of atomic weight. Silver has an atomic weight of 108 grams/mole and Chlorine is 35.4 grams/mole. This makes AgCl 108 + 35.4 = 143.4 grams/mole. The % Chlorine is the atomic weight of Chlorine divided by the molecular weight of AgCl. 1 mole of AgCl would contain 35.4 grams / 143.4 grams = 25% Chlorine by weight. 1.22 grams AgCl would contain (0.25)*(1.22) = 0.30 grams of Cl. To find the Chlorine in the unknown, divide the weight of Chlorine from the experiment by the initial weight of the unknown. 0.30 grams / 0.63 grams = 0.48 = 48% Cl by weight.
On the periodic table, the atomic weight listed for most of the elements is the average of that element's isotopes. Chlorine has 2 common isotopes: Chlorine-35 (75.77% of all chlorine) and chlorine-37 (24.23%). This has two extra neutrons. This works out to an average of 35.453.
Chlorine (Cl), atomic number 17.
Chlorine is a non metal element. Chlorine atomic mass is 35.453.
the equivalent weight of chlorine is 35.453, which is also it's atomic weight.
It has an atomic mass of 35.4527
The atomic weight (not mass) of chlorine is now [35,446; 35,457]. I don't understand "no chlorine with mass exist in nature".
No. chlorine has an atomic weight 0f 35.45. and has an atomic number (number of pprotons) of 17. It has two naturally occuring isotopes chlorine-35 and chlorine -37. It is the presence of these that causes the fractional atomic weight
No, electrons only make a negligible contribution to atomic weight. On the periodic table the atomic weight listed for most of the elements is the average of that element's isotopes. Chlorine has 2 common isotopes: Chlorine-35 (75.77% of all chlorine) and chlorine-37 (24.23%) This works out to an average mass of about 35.5.
Atomic weight of carbon: [12,0096; 12,0116]. Atomic weight of chlorine: [35,446; 35,457]. The molar mass of chlorine is greater; rounded 35,45 g/mol.
The atomic number of chlorine is 17.The atomic weight (after the IUPAC rules weight is the correct word in thiscase, for elements, not mass; mass is used only for isotopes) of chlorine is[35,446; 35,457], after the IUPAC tables, 2009 edition.
The atomic weight of chlorine is 35,45.The atomic weight of chlorine is approximately 35.5 g/mol. An addition of electron is a negligible weight difference. Therefore, the mass is considered to remain the same at 35.5 grams per mole.
For the determination of the atomic weight (not mass) of chlorine we need to know the isotopic composition of Cl and the atomic masses of the isotopes.
The atomic weight (not mass) of sodium is: 22,989 769 28.The atomic weight (not mass) of chlorine is: 35,45.
