How much does one chlorine molecule weigh?
70 grams
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 do you calculate the weight of chlorine?
35.453 u
Chlorine/Atomic mass
How many molecules are there in 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).
What is the molecular weight of Cl2?
69.9377054

How do you calculate molecules?
Explanation: Determine the mass of the substance, and its molar mass. Divide the given mass by its molar mass to get moles, then multiply times 6.022×1023molecules1mol .
What is the molar mass of chlorine?
What is the molecular weight of cl2?
What is the molar mass of chlorine molecule?
35.45 g/mol
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 .
How many chlorine atoms are there in Cl2?
two Chlorine atoms
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 molecules of Cl2 are in 42.0 g of Cl2?
42.0 g Cl2 contains 6.022× 1023 molecules Cl2.
What is the molecular structure of Cl2?
In the case of Cl2, there is no central atom, so no lone pair on it, and Cl2 has only one bonded pair of electrons that is between two chlorine atoms. So, the molecular geometry of Cl2 is linear.
What is the molecular weight of chlorine in grams?
›› Chlorine molecular weight. Molar mass of Cl = 35.453 g/mol. Convert grams Chlorine to moles or moles Chlorine to grams ›› Percent composition by element
What is the density of chlorine at room temperature?
Liquefies at -35°C and room pressure. Readily liquefied by pressure applied at room temperature. Density (as a liquid) 13.0 lb / gal. Contact with unconfined liquid can cause frostbite by evaporative cooling.
Which is the element with the atomic number CL?
Laboratory Chemical Safety Summary (LCSS) Chlorine is an element with atomic symbol Cl, atomic number 17, and atomic weight 35, and member of the halogen family. Chlorine is a commonly used household cleaner and disinfectant. CHLORINE is a greenish yellow gas with a pungent suffocating odor.
How is the molecular weight of a compound calculated?
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.
