What is the mass of 2.50 X 104 molecules of nitrogen gas?
To calculate the mass of 2.50 x 10^4 molecules of nitrogen gas, you need to know the molecular weight of nitrogen. The molar mass of nitrogen (N2) is approximately 28.02 g/mol. Using this information, you can then calculate the mass of 2.50 x 10^4 molecules of nitrogen gas.
What is the mass of 2.84 x 1022 molecules of nitrogen gas?
To calculate the mass of 2.84 x 10^22 molecules of nitrogen gas, you first need to convert molecules to moles using Avogadro's number. Then, you can use the molar mass of nitrogen (28.02 g/mol) to determine the mass. The mass of 2.84 x 10^22 molecules of nitrogen gas would be approximately 5.04 grams.
How much mass would a mole of nitrogen molecules contain?
One mole of nitrogen molecules contains approximately 28 grams (since the atomic mass of nitrogen is approximately 14 g/mol).
How many molecules are in 140gm of nitrogen gas?
To determine the number of molecules in 140g of nitrogen gas, you first need to convert the mass of nitrogen gas to moles using its molar mass. The molar mass of nitrogen gas (N2) is 28 g/mol. Once you have the number of moles of nitrogen gas, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules present in 140g of nitrogen gas.
Do air molecules have mass?
Yes, air molecules do have mass. Air is made up of various gases such as nitrogen, oxygen, and carbon dioxide, and each of these gas molecules contributes to the overall mass of the air.
What mass of oxygen contain same number of molecule as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.

How many nitrogen molecules are in 12.88g of nitrogen gas?
To determine the number of nitrogen molecules in 12.88g of nitrogen gas, you first need to convert grams to moles using the molar mass of nitrogen (28.02 g/mol). Then, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in that number of moles.
What mass of oxygen contain the same number of molecules as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen.

How many molecules are in 67.9 g N?
To find the number of molecules in 67.9 g of nitrogen (N), you first need to convert the mass (in grams) to moles using the molar mass of nitrogen (28.02 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules.
How many molecules are in 28 grams of nitrogen gas?
To calculate the number of molecules in 28 grams of nitrogen gas, you first need to determine the number of moles of nitrogen gas using its molar mass. The molar mass of nitrogen gas (N2) is 28 g/mol. Therefore, 28 grams of nitrogen gas is equivalent to one mole. One mole of a gas contains approximately 6.022 x 10^23 molecules, which is Avogadro's number. So, 28 grams of nitrogen gas would contain approximately 6.022 x 10^23 molecules.
How many grams of nitrogen dioxide must react with water to produce 5.00x10 22 molecules of nitrogen monoxide?
To produce 5.00x10^22 molecules of nitrogen monoxide (NO), you need an equal number of molecules of nitrogen dioxide (NO2). With the balanced chemical equation 2NO2 + H2O → 2NO + 2HNO3, you can calculate the mass of nitrogen dioxide needed using the molar masses of NO2 and NO.
