Chlorine gas is heavier than oxygen. Chlorine gas has a molar mass of 70.9 g/mol, while oxygen has a molar mass of 32 g/mol. This difference in molar mass causes chlorine gas to be heavier and therefore it will tend to sink below oxygen in a mixture.

Atomic weight of carbon: [12,0096; 12,0116]. Atomic weight of chlorine: [35,446; 35,457]. The molar mass of chlorine is greater; rounded 35,45 g/mol.
0.560 moles × 35.453 grams/mole = 19.85 grams
The answer is it's atomic mass converted to grams... Chlorine has an atomic mass of 35.45 So 1 mol of chlorine would be 35.45g you have 142g of it, so you divide 142 by 35.45 and get 4.005 moles of chlorine
To calculate the number of moles in 15g of chlorine gas, you need to use its molar mass. The molar mass of chlorine is approximately 35.5 g/mol. Divide the given mass by the molar mass to find the number of moles. For 15g of chlorine gas, you will have about 0.42 moles.
Chlorine gas is heavier than oxygen. Chlorine gas has a molar mass of 70.9 g/mol, while oxygen has a molar mass of 32 g/mol. This difference in molar mass causes chlorine gas to be heavier and therefore it will tend to sink below oxygen in a mixture.

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.
The reaction between sodium and chlorine gas occurs in a 1:1 molar ratio. The molar mass of chlorine gas is 71 g/mol. To find the mass of chlorine that will react with 92.0 g of sodium, first convert 92.0 g of sodium to moles, then use the 1:1 ratio to calculate the mass of chlorine gas needed.
To find the number of moles in 17.75 g of chlorine gas (Cl₂), first determine the molar mass of Cl₂. Chlorine has an atomic mass of approximately 35.45 g/mol, so Cl₂ has a molar mass of about 70.90 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), we calculate: moles = 17.75 g / 70.90 g/mol ≈ 0.250 moles. Therefore, there are approximately 0.250 moles of chlorine gas in 17.75 g.
Atomic weight of carbon: [12,0096; 12,0116]. Atomic weight of chlorine: [35,446; 35,457]. The molar mass of chlorine is greater; rounded 35,45 g/mol.
The molar mass of chloroform (CHCl3) is 119.38 g/mol. The molar mass of chlorine in CHCl3 is 35.45 g/mol. To calculate the mass percent of chlorine, divide the molar mass of chlorine by the molar mass of chloroform and multiply by 100%. Therefore, the mass percent of chlorine in chloroform is 29.7%.
To calculate the number of moles in 140 g of Cl2, divide the given mass by the molar mass of Cl2. Number of moles = Mass / Molar mass = 140 g / 70.9 g/mol = 1.97 moles. Therefore, there are 1.97 moles of chlorine gas in 140 g of Cl2.
The mass of 1,00 L of chlorine gas is 3,2 g at 20 oC.
To calculate the mass percent of chlorine in chloroform (CHCl3), you would first find the molar mass of the compound, which is 119.38 g/mol. Then, determine the molar mass of chlorine in the compound, which is 35.453 g/mol. Calculate the mass percent of chlorine by dividing the molar mass of chlorine by the molar mass of the compound and multiplying by 100. In this case, the mass percent of chlorine in chloroform is about 29.7%.
Sodium reacts with chlorine gas in a 1:1 molar ratio. Thus, for 2.00 mol of sodium, 2.00 mol of chlorine gas is required. The molar mass of chlorine gas is approximately 70.91 g/mol. Therefore, the mass of chlorine gas needed is 2.00 mol x 70.91 g/mol = 141.82 grams.
