Best answer: How many chlorine atoms are in 2 moles of chlorine?

How many atoms of chlorine are in a mole of chlorine?

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. 6.02 × 1023 molecules of hydrogen would weigh 2 grams. An equal number of chlorine molecules would weigh 70 grams.

What is the mass of 2 moles of chlorine molecule?

Chlorine gas Cl 2, has a relative molecular mass of 71 because it is made up of two Cl atoms, each of Mr 35.5. A mole of chlorine gas has a mass of 71g, and contains two moles of chlorine atoms, each of mass 35.5g.

What is the mass of 2 mole of CL2?

Molecular mass of CL2=2×35. 453amu=70.906amu.

How do you find moles of chlorine?

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 atoms of chlorine are there?

But the question asked is “how many atoms are present?” Because each molecule of Chlorine contains two atoms, the answer is 2 x 1.607 x 1024 atoms are present = 3.22 x 1024 atoms.
