'N' as nitrpogen exists as the molecular gas N2
Using the moles equation
moles = mass /Mr
moles(N2) = 11.7 / 28 = 0.417857142
Now remember the Avogadro Number.
1 mole contains 6.022 x 10^(23) atoms/molecules.
Hence
Multiplying
6.022 x 10^(23) X 0.417857142 = 2.516 x 10^(23) molecules. The Answer!!!!!!

How many grams of iodine dissolved in water for 0.02 n iodine?
To calculate the grams of iodine dissolved in water for 0.02 N iodine, you need the molar mass of iodine, which is approximately 254 g/mol. With this information, you can use the formula: Grams = Normality (N) * Equivalent weight. Therefore, for 0.02 N iodine: Grams = 0.02 * 254 = 5.08 grams of iodine.
How many molecules of HCI will be required to have 10 grams of it?
To calculate the number of molecules of HCl in 10 grams, you first need to determine the molar mass of HCl, which is about 36.5 g/mol. Next, use the formula n = m/M, where n is the number of moles, m is the mass in grams, and M is the molar mass. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many grams of n are in 34.0g of n20?
To find the grams of nitrogen (N) in 34.0g of N2O, you need to consider the molar mass of N2O (44.02 g/mol) where 28.02 g out of 44.02 g is nitrogen. Therefore, in 34.0g of N2O, there are 34.0g * (28.02g/44.02g) = 21.6g of N.

What is the mass in grams of 6.022 x 1023 N atoms of mass 14.01 amu?
The molar mass of any element is its atomic weight (amu) in grams, and 1 mol of any element is 6.022 x 1023 atoms. Therefore, the mass in grams of 6.022 x 1023 atoms of N = 14.01g N.
How many grams are in 2.4 x 1023 molecules of P2O5?
n = gmol = N molecules / N Avogadro n = ( 2.4 x 10^23 molecules ) / ( 6.022 x 10^23 molecules per gmol ) n = 0.3985 gmol m = ( n ) ( M ) m = ( 0.3985 ) ( 141.94 g per gmol ) = 56.6 g <----------------------
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.
What is three consecutive integers whose sum is 117?
Three consecutive integers whose sum is 117 are 38, 39, and 40. N + (N+1) + (N+2) = 117 3N + 3 = 117 3N = 114 N = 38
How many grams are in 8.2 x 10(22) atoms of N2I6?
To find the mass of 8.2 x 10²² atoms of N₂I₆, first determine the number of molecules, which is equal to the number of atoms divided by the number of atoms in one molecule of N₂I₆ (which contains 8 atoms). This gives approximately 1.025 x 10²² molecules. The molar mass of N₂I₆ is about 360.8 g/mol. Therefore, the mass in grams can be calculated by multiplying the number of molecules by the molar mass and dividing by Avogadro's number (6.022 x 10²³), resulting in approximately 57.4 grams.
How many grams are in 8.2 times 10exponets22 molecules of N2i6?
To find the mass in grams of 8.2 × 10²² molecules of N₂i₆, we first need to determine the molar mass of N₂i₆. Assuming N₂i₆ refers to a compound of nitrogen (N) and iodine (I), we would calculate its molar mass based on the atomic weights of nitrogen (approximately 14 g/mol) and iodine (approximately 127 g/mol). Once we have the molar mass, we can convert the number of molecules to moles using Avogadro's number (6.022 × 10²³ molecules/mol) and then multiply by the molar mass to find the mass in grams. Without the exact formula or molar mass, the exact mass cannot be calculated here.
