How many moles are contained in 4.67 L sample of gas 33 degrees Celsius and 199 kpa?
how many moles are contained in 4.67 L sample of gas at 33 degrees celcius and 199 kpa
What two elements are contained in all inorganic molecules?
Inorganic molecules contain elements such as hydrogen and oxygen. These elements contribute to the basic structure and properties of many inorganic compounds.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many CFC molecules are being liberated on an average in one hour from an air condition?
None. They are contained within th eunit and do not leave unless the unit is damaged.
How many molecules are contained in a 6.95 g sample of dimethylmercury?
1.814*1022
How many molecules are contained in a 5.20 g sample of dimethylmercury?
The answer is 1,357.10 ex.23 molecules.
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 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 molecules are contained in a 5.20-g sample of dimethylmercury?
To calculate the number of molecules in a 5.20-g sample of dimethylmercury, you first need to determine the molar mass of dimethylmercury (Me2Hg). Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert the mass to moles and then to molecules.
How many molecules are contained in a 6.30g sample of dimethylmercury?
To find the number of molecules in a 6.30g sample of dimethylmercury, you need to know the molar mass of dimethylmercury (the molecular formula is C2H6Hg) and Avogadro's number. First, calculate the number of moles in the sample by dividing the mass by the molar mass. Then, use Avogadro's number to convert moles to molecules by multiplying by 6.022 x 10^23.
How many molecules are contained in a 4.85g sample of dimethylmercury?
To find the number of molecules in a sample of dimethylmercury, you need to calculate the number of moles first. The molar mass of dimethylmercury (Hg(CH3)2) is 230.61 g/mol. Then, divide the mass of the sample by the molar mass to get the number of moles. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules.
How many molecules are contained in a 5.00 g sample of dimethylmercury?
To determine the number of molecules in a sample, you need to know the molar mass of the compound. For dimethylmercury, the molar mass is approximately 230.6 g/mol. You can then use the formula n = m/M, where n is the number of moles, m is the mass of the sample, and M is the molar mass, to calculate the number of molecules in the sample.
How many molecules are contained in a 4.75-g sample of dimethylmercury?
To calculate the number of molecules in a sample, you need to know the molecular weight of the substance. The molecular weight of dimethylmercury is approximately 214.77 g/mol. Using this information, you can determine the number of moles in the 4.75-g sample and then convert that to the number of molecules using Avogadro's number.
How many molecules are contained in a 4.40-g sample of dimethylmercury?
To determine the number of molecules in a sample, you need to know the molar mass of the substance. The molar mass of dimethylmercury (CH3)2Hg is approximately 230.65 g/mol. Utilizing the formula: moles = mass/molar mass, and then using Avogadro's number (6.022 x 10^23 molecules/mol), you can calculate the number of molecules in the sample.
How many molecules are contained in a 4.30 g sample of dimethylmercury?
To determine the number of molecules in a 4.30 g sample of dimethylmercury (MM = 230.64 g/mol), you need to first calculate the number of moles using the formula: moles = mass / molar mass. Then, you can convert moles to molecules using Avogadro's number (6.022 x 10^23 molecules/mol). So, for dimethylmercury: moles = 4.30 g / 230.64 g/mol, then molecules = moles x 6.022 x 10^23.
How many Molecules are contained in 0.900 mol O2?
There are (5.41 \times 10^{23}) molecules of (O_2) in 0.900 moles.
