In one mole of any element, there are 6.022*1023 atoms, Avogadro's number.
3 mol Cl * (6.022*1023 atoms Cl/mol Cl) = 1.8066*1024 atoms Cl
Therefore, there are approximately 1.807*1024 atoms in three moles of chlorine.
Be careful with this answer because the question probably carries hidden in it the expectation that you know that chlorine gas is diatomic. If that is the case, what is really being asked is how many atoms are in 3 moles of chlorine gas. When you answer that question be certain that you clarify your understanding. 3 moles of chlorine gas (Cl2) has 6 moles of chlorine atoms. 6 x NA will give you the answer.
3.01 X 1023 atoms of chlorine (1 mole Cl/6.022 X 1023)(35.45 grams/1 mole Cl)
= 17.7 grams of chlorine
======================as indicated, half of Avogadro's number yields half the mass
3 x 6.022 x 1023 = 18.066 x 1023 = 1.8066 x 1024
I am assuming you mean 3.61 x 1024 atoms.
1 mole of Cl atoms = 6.022 x 1023 atoms Cl (Avogadro's number)
3.61 x 1024 atoms Cl x (1mol Cl/6.022 x 1023 atoms Cl) = 5.99mol Cl
The mass of 3,01.10e24 molecules of Cl2 is 354,17 g.
70.906 g mol-1
5.99 is the WRONG answer!! It's 12.0 mol Cl.
355g
Halogen molecules are not polar.
The rate of diffusion of a gas depends on the weight of the gas molecules. The heavier the molecules, the slower they move - the lighter the molecules, the faster they move. Nitrogen molecules weigh about 28 units. Chlorine molecules weigh 71 units. So we would expect nitrogen to diffuse more quickly than chlorine.
Hydrogen, Nitrogen, Oxygen, Chlorine and Fluorine are diatomic gases. Bromine is a diatomic liquid. Iodine is a diatomic solid. (at room temperature)
Thiosulfate: 2 S2O32- --> S4O62- + 2e-equivalency to:Chlorine: 1 Cl2 + 2e- --> 2Cl-31.6 ml * 0.141 mmol/ml S2O32- = 4.456 mmol S2O32-= 4.456 *(2 electron / 2 S2O32-) = 4.456 mmol (electrons) == 4.456 *(1 Cl2 / 2 electron) = 2.228 mmol Cl2 == 2.228 * 70.90 mg/mmol Cl2 = 158 mg == 0.158 g Chlorine
Molecules are the combination of two or more atoms which may exist free in gaseous form or in solutions, the ionic compounds are not the molecular compounds because their one unit can not exists freely but as the crystal lattice.
Cl2 is a diatomic molecule.
How many molecules are present in 42.0g of Cl2
The atomic mass of Cu is: 63.546 g.mol The atomic mass of Cl2 is: 35.453 g.mol So your answer would be: Cu has the largest Atomic mass.
No, it is a gas consisting of Cl2 molecules (a diatomic element)
The gram molecular mass of Cl2 is 70.906, twice the atomic mass of chlorine atoms. Therefore, 79.3 grams of Cl2 contains 79.3/70.906 or 1.12 moles, to the justified number of significant digits.
London forces are present in chlorine molecules.
Halogen molecules are not polar.
253.81 g mol-1
The molar mass for ZnCl2 is 136.286g/mole.
Of the molecules given by formula in the question (after proper capitalization where needed), only Cl2 is covalently bonded.
Cl2 has a molar mass of about 71 g/moleArgon has molar mass of about 40 g/mole Thus, Argon will diffuse faster than Cl2 gas, or put another way, Cl2 will diffuse slower than argon.
