We assume that the quantity 56.22 is in grams. The formula mass of CF2Cl2 is 12.0 + 2(19.0) + 2(35.5) = 121.0Amount of CF2Cl2 = mass of pure sample/molar mass = 56.22/121.0 = 0.465mol There are 0.465 moles of CF2Cl2 in a 56.22 pure sample.
To calculate the number of molecules in a sample of dimethylmercury, you would first need to determine the number of moles in the sample using the molar mass of dimethylmercury. Then you can use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules.
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
To determine the number of molecules in a sample, we need to know the molar mass of dimethylmercury (C2H6Hg). The molar mass of dimethylmercury is approximately 230.62 g/mol. Using this molar mass, we can calculate that there are approximately 2.23 x 10^22 molecules in a 7.85-g sample of dimethylmercury.
To find the number of moles in CF2Cl2, you would need to know the mass of the sample. Once you have the mass, you can use the formula Moles = Mass / Molar Mass to calculate the number of moles. The molar mass of CF2Cl2 is 120.91 g/mol.
We assume that the quantity 56.22 is in grams. The formula mass of CF2Cl2 is 12.0 + 2(19.0) + 2(35.5) = 121.0Amount of CF2Cl2 = mass of pure sample/molar mass = 56.22/121.0 = 0.465mol There are 0.465 moles of CF2Cl2 in a 56.22 pure sample.

5745 minutes ÷ 60 minutes/hour = 95.75 hours (95 hours and 45 minutes)
The answer is 1,357.10 ex.23 molecules.
To find the number of moles in 1 kg of CF2Cl2, you first need to calculate the molar mass of CF2Cl2. Carbon has a molar mass of 12.01 g/mol, fluorine has a molar mass of 19.00 g/mol, and chlorine has a molar mass of 35.45 g/mol. Adding these up gives a molar mass of 120.91 g/mol for CF2Cl2. Next, convert 1 kg to grams (1000 g). Finally, divide 1000 g by the molar mass of CF2Cl2 to find the number of moles in 1 kg of CF2Cl2.
5745L equates to 1,517.67 US gallons.

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.
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
