How many moles are in 56.22 CF2CL2?
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.
How many molecules are contained in a 4.15-g sample of dimethylmercury?
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.
How many molecules of water does a 50g sample of H2O have?
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.
How many molecules are contained in a 7.85-g sample of dimethylmercury?
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.
How many moles are in CF2Cl2?
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.
How many moles are in 56.22 CF2CL2?
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.
How many hours is 5745 minutes?
5745 minutes ÷ 60 minutes/hour = 95.75 hours (95 hours and 45 minutes)
How many kilograms of chlorine are in 25 kg of CF2Cl2?
10kg
How many molecules are contained in a 5.20 g sample of dimethylmercury?
The answer is 1,357.10 ex.23 molecules.
How many moles are in 1 kg of CF2Cl2?
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.
How many liters is 5745 In gallons?
5745L equates to 1,517.67 US gallons.
How many molecules are contained in a 4.15-g sample of dimethylmercury?
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.
How many molecules are contained in a g sample of dimethylmercury?
1.24*10^22
How many moles of molecules does a 36g sample of carbon briquets contain?
3
How many molecules are contained in a 6.95 g sample of dimethylmercury?
1.814*1022
How many types of molecules with different masses exist in a sample of chlorine gas if the same exists entirely as diatomic molecules?
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.
How many molecules of water does a 50g sample of H2O have?
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.
