http://en.wikipedia.org/wiki/Chlorine 1 mol of chlorine (Cl2) weighs (2*35.45 =)70,90 grams 134,5 grams of chlorine is (134,5/70,9 =) 1,897 mol of chlorinegas. 1,897 * 6,02 * 10^23 = 1,142 * 10^24 molecules of Cl2
Multiply the moles given, by the atomic mass of chlorine and you have your answer. (3.55 Grams)
117 grams of sodium chloride (NaCl) is equivalent to 117 grams of chlorine gas because each molecule of NaCl contains one sodium atom and one chlorine atom.
Since 1 mole is (6.022×1023 molecules)/(mol), so 9.02 x 1023 molecules would be 1.4978... mol
In a sample of chlorine gas, all molecules are diatomic composed of two chlorine atoms. This means there is only one type of molecule in the sample, with a molecular formula Cl2.
To convert molecules to grams, first find the molar mass of NCl3: Nitrogen (N) has a molar mass of 14.01 g/mol, and chlorine (Cl) has a molar mass of 35.45 g/mol. Therefore, the molar mass of NCl3 is 14.01 + (3 * 35.45) = 120.36 g/mol. Now, use this molar mass to convert molecules to grams: 8.2 x 10^22 molecules * (1 mol / 6.022 x 10^23 molecules) * 120.36 g/mol ≈ 16.06 grams.
1000 g = 1 kg ⇒ 1345 g = 1345 ÷ 1000 kg = 1.345 kg
1345
Chlorine gas (at standard temperature and pressure) consists of diatomic molecules. Therefore, in the specified number of molecules of chlorine gas there are 1.364 X 1025 atoms. The gram atomic mass of chlorine, which by definition consists of Avogadro's Number of atoms, is 35.453. Therefore, the mass of the specified number of molecules of chlorine gas is 35.453 X [(1.364 X 1025)/(6.022 X 1023)] or 803 grams, to the justified number of significant digits.
There are approximately 1.18 cups of granulated chlorine in 120 grams.
To find the answer, we multiply the 7 grams of NaCl by the ratio of the molar mass of chlorine over the molar mass of sodium chloride. By doing this, we find that there are about 4.25 grams of chlorine in 7 grams of NaCl.
75 g sodium chloride contain 29,75 g sodium.

Multiply the moles given, by the atomic mass of chlorine and you have your answer. (3.55 Grams)
25 grams / (17 grams/mole) x 6.022x1023 molecules/mole = 8.9x1023 molecules
117 grams of sodium chloride (NaCl) is equivalent to 117 grams of chlorine gas because each molecule of NaCl contains one sodium atom and one chlorine atom.
Phosphorus trichloride (PCl₃) contains three chlorine atoms per molecule. Therefore, in four molecules of phosphorus trichloride, the total number of chlorine atoms is 4 molecules × 3 chlorine atoms/molecule = 12 chlorine atoms. Thus, there are 12 chlorine atoms in four phosphorus trichloride molecules.
To find the number of chloride molecules in 35.5 grams of chloride gas, you first need to calculate the number of moles of chloride gas using its molar mass (Cl2 = 70.906 g/mol). Then, use Avogadro's number (6.022 x 10^23) to convert moles to molecules. This calculation will give you the number of chloride molecules in 35.5 grams of chloride gas.
