What is the MM of chlorine?
The actual molecular mass of chlorine = 177.7×10−24g.
What is the molar mass of a chlorine molecule?
71 g/mole
We know that the atomic mass of chlorine is 35.5 g/mole. We have also discussed above that chlorine exists as a diatomic molecule. Therefore, its molecular mass is twice its atomic mass. So the mass of 1 molecule of chlorine will be 35.5×2 g/mole = 71 g/mole.
What is the relative molecular mass of a chlorine molecule Cl2?
It is known that the chlorine molecule is diatomic – Cl2, then the relative atomic mass of the chlorine molecule will be equal to: Ar (Cl2) = 35,453 · 2 = 70,906 amu. The relative molecular mass of the chlorine molecule will be 70,906, and the molar mass: M (N2) = Mr (Cl2) · 1 mol = 70,906 g/mol or just 71 g/mol.
What is the formula for Cl2?

How do you find the mass of Cl 35?
About one quarter of all chlorine atoms have 20 neutrons, giving those atoms a mass number of 37….Sample Problem: Calculating Atomic Mass.
| chlorine-35 | 0.7577 × 34.969 = 26.50 amu |
|---|---|
| chlorine-37 | 0.2423 × 26.966 = 8.957 amu |
| average atomic mass | 26.50 + 8.957 = 35.45 amu |
How many grams is Cl2?
Note that 6.022⋅1023 is also known as Avogadro’s number, and it can be referred to as the number of molecules in one mole of that substance. Also, I calculated 70.9 because 35.45 g/mol (the mass of one Chlorine atom) times 2 is 70.9 g/mol (Cl2 has two Chlorine atoms).
How do you find the mass of CL?
Answer: To find the atomic mass of chlorine, the atomic mass of each isotope is multiplied by the relative abundance (the percent abundance in decimal form) and then the individual masses are added together. The atomic mass of chlorine is 35.45 amu.
What is the mass of 2.5 moles of Cl2?
Answer: Cl2 contains two Cl atom so molar mass will be 35 . 5 x2 that is 71 GRAM means 0ne mole of Cl2 has 71 gram so 2.5 mol will be equal to 2.5×71. Gram.
Is chlorine formula Cl or cl2?
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature.
What is the atomic mass of Cl2?
Atomic mass of Cl atom is 35 5 u. Cl2 contains two Cl atom so molar mass will be 35 .5 x2 that is 71 GRAM means 0ne mole of Cl2 has 71 gram so 2.5 mol will be equal to 2.5×71.
What is the weight of Cl2?
Answer Wiki. The molar weight of chlorine gas (Cl2) is 70,9 grams per mole, with one mole being 6.022 * 10^23 molecules (Avogadro’s Number).
What is the molar mass of MgCl2?
The average molar mass of the chemical compound magnesium chloride is 95.211 grams per mole
Is Cl2 an element?
