Yes, chlorine gas is Cl2. There are 7 diatomic molecules (H,O,N,Cl,Br,I,F), so whenever these are gases or "exist naturally", you should use the subscript 2.
How many moles is Cl2?
Cl2 is made up of 2 chlorine atoms. Each chlorine atom has a molar mass of 35.5 g/mol (from the periodic table). Thus, the molecule Cl2 has a molar mass of 71.0 g/mol.
What is true about the molar mass of chlorine gas Cl2?
The atomic mass of chlorine is 35.5u . The molecular mass of chlorine (Cl2 C l 2 ) is m=2×35.5u=71.0u m = 2 × 35.5 u = 71.0 u . Hence, the molar mass of chlorine gas is M=71.0g/mol M = 71.0 g / m o l . In other words, a mole of chlorine gas occupies 71.0g in mass.
What is the mole of Cl2?
Hence, the answer is 3.33⋅1023 molecules of 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 many grams are in a mole of Cl?
The mass of one mole of chlorine gas is its molar mass, and can be determined by multiplying its subscript by the molar mass of chlorine (atomic weight on the periodic table in g/mol), which is 35.45 g/mol .
What is the equivalent weight of cl2?
Therefore, molar mass of Chlorine gas, (C{{l}_{2}}) = 2 x 35.5 u = 71 u. Therefore, the answer is – option (a) – The equivalent weight of chlorine molecule in the given reaction is 42.6.
Is cl2 chlorine or chloride?
Chlorine (CL2) Chlorine is the chemical element with atomic number 17 and symbol Cl. It is a halogen, found in the periodic table in group 17 (formerly VII, VIIa, or VIIb).
What is Cl vs Cl2?
Chlorine is a chemical element having the symbol Cl and atomic number 17. Cl2 is a molecule consisting of two atoms whereas Cl3 is an anion consisting of three atoms. Hence, Cl3 has a negative electrical charge, but Cl2 is neutral.
What is the equivalent weight of Cl2?
Therefore, molar mass of Chlorine gas, (C{{l}_{2}}) = 2 x 35.5 u = 71 u. Therefore, the answer is – option (a) – The equivalent weight of chlorine molecule in the given reaction is 42.6.
Is Cl2 one mole or two?
Hence, the answer is 3.33⋅1023 molecules of 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 many moles are in chlorine gas?
A conveniently measured amount of any element that equals the mass in grams of that element is called a mole. One mole of hydrogen weighs 2 grams. One mole of chlorine weighs 70 grams. Just like a dozen equals twelve, a mole equals Avogadro's number of atoms or 6.02 × 1023.
How many grams is Cl2?
Each chlorine atom has a molar mass of 35.5 g/mol (from the periodic table). Thus, the molecule Cl2 has a molar mass of 71.0 g/mol. 25 years of experience teaching high school chemistry! From the periodic table, we can determine the molar mass of Cl2 is 70.90 g/mol.

What is the equivalent mass of HCl?
85.1g Now equivalent mass is given as the molecular weight divided by the n-factor. Therefore, the equivalent mass of HCl is 85.1g.
How do you find the equivalent mass?
To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid's molar mass by the number of protons.
