2 (atoms N / molecule N2) * 8.5*10+24 (molecules N2) / 6.02*10+23 (atoms N / mole N-atoms) = 28 mole N-atoms
This is an unknown number of atoms or molecules.

1. Generally molecules are formed from atoms of different chemical elements. 2. But molecules containing atoms of only one element exist: diatomic molecules of Cl, F, Br, I, N, O, H, P, S; these molecules are called homonuclear.
Each bio-molecule has a specific chemical formula and a different number of atoms; generally bio-molecules contain C, H, O, N.
chlorofluorocarbons are of many molecules their possible formulas can be as follows C2H2F2 C2H3F C2HF3 number of molecules can bhi calculated by formula No of atoms= n + (2n+2)= 3n+2 where n is the number of carbon atoms. and when number of carbon atoms are more than 2 this formula is appliead and for 2 carbons total number of atoms are 6.
As we know that in 22.4lt there is one mole of any gaseous molecules. Hence in water there are avogadro no.(N) of molecules of water and in each of them are two hydrogen atoms so No. of hydrogen atoms in 22.4lt = 2 X N so No. of hydrogen atoms in 1lt water = (2 X N)/22.4

1 mole of a substance contains 6.02 x 1023 particles (molecules, atoms ...). This number (6.02 x 1023) is called the Avogadro's constant. the forumula: n = N / NA (NA is the Avogadro's number / constant; N = number of particles (molecules, atoms...) in the substance)
N and H atoms will form covalent bonds together. N-H molecules will hydrogen bond together.
The atomic mass of the N atom is 14.0. This means that 1 mole of N atoms weighs 14.0g.Mass of 5.0 moles of N atoms (or 2.5 moles of diatomic nitrogen molecules, N2)= 5.0 x 14.0= 70g
Multiply 8.7 by avagadros number to get the number of molecules. 8.7x6.02x1023=5.24x1024 molecules of NO. as there is 1 atom of N and one of O for each molecule there are 5.24x1024 atoms of each element. this means that the total number of atoms is 2x5.24x1024 = 1.05x1025 atoms
living things would be a person a plant anything that needs air to breathe or food to eat. non living things would be a rock?
narwals and nut trees!
Many organic molecules necessary to life all contain nitrogen (N) atoms. Amino acids that comprise proteins, cellular energy from ATPs, and the genetic blueprint of DNA all contain N.
n(Au)= 1.5g/M(Au)= 1.5/196.97 = 0.00761537mol n(Au) = No(Atoms)/N(a)therefore N(Atoms)=n(Au) x N(a)N(atoms) = 0.00761537mol x 6.02x10^23mol*-1N(atoms) approximatly equals 4.6x10^21 atoms
Neither. Due to the lone pairs on the N and P atoms, both molecules have a trigonal pyramidal shape.
it isn't made up of atoms or molecules, and havent got a clue what nitrogen is!!! ------------- Nitrogen is a natural chemical element with the symbol N; nitrogen exist, as other many gases, as a diatomic molecule - N2.
A covalent molecules are molecules formed by covalent bond(sharing of electrons) b/n nonmetals with the exception of amonium ion to satisfy octate electron.
Because N exist as diatomic molecule in nature.It is not a noble gas
Sort of true. Actually only four make up most of all living things (C O H N), and ten make up 99.9% of living matter but tiny traces (even a dozen or so atoms) of exotic elements are used (and required) by "higher organisms".
Ammonia = NH3 and has a molar mass of 17.031 g/molmoles NH3 = 63.9 g x 1 mol/17.031 g = 3.752 molesmolecules NH3 = 3.752 moles x 6.02x10^23 molecules/mole = 2.259x10^24 moleculesEach molecule of NH3 has 4 atoms (1 N + 3 H), thus....number of atoms = 4 atoms/molecule x 2.259x10^24 molecules = 9.04x10^24 atoms (to 3 sig figs)
Because it is full of dissolved salt which makes the density of things lighter, and therefore makes them float.
This is actually the reason they are called Carbo(n)hydrates .... They usually contain C H and O atoms ...
