Molar mass of Fe(NO3)2 is 55.85 + 2(14.00 + 3(16.00)) = 179.85 g/mol Therefore, number of moles of Fe(NO3)2 present is 53.55/179.85 = 0.2977 mol For each molecule of Fe(NO3)2, there are two atoms of nitrogen associated with it. Therefore, there are 0.2977*2 = 0.5954 mol of nitrogen atoms
6.226 x 10^28 atoms of Nitrogen approximately mole = 6.226 X 10^28 objects Nitrogen exists as a diatomic molecule, so in 0.5 moles of diatomic nitrogen gas there are exactly 1 moles worth of molecules, therefore the number of atoms in 0.5 moles of nitrogen gas is equal to the value of the mole which is approximately 6.226 x 10 ^ 28 atoms
The number of atoms is 15,11.10EX23.
Are you familiar with mole concept. Well according to it 1 mole of anysubstance contains 6.023e23. First calculate the molecular mass of glucose which is (6*12)+12+(6*16)=180=y gm(say). Now find the mass of the sample glucose say x gm. Calculate the number of moles of glucose present which is found out by x/y. If its exactly 1 mole then the number of carbon atoms present are 6.023e23. Else use unitary method to find out for other values. For your mentioned number of carbon atoms the 0.0021 moles of glucose present.
Whatever be the substance the one gram mole of that substance would have 6.023 x 1023 atoms or molecules or ions in it. Hence to get the mole just divide the number given by 6.023 x 1023
We know from looking at the molecular formula that one mole of molecules of H2SO4 contains 2 moles of atoms of hydrogen, 1 mole of atoms of sulfur and 4 moles of atoms of oxygen.
Since each N2O molecule contains 2 nitrogen atoms, the number of moles of N2O molecules would be half of the moles of nitrogen atoms. Therefore, in this case, there would be 2.615 moles of N2O molecules present in the sample.
1.38 moles of nitrogen equal16,62110876532.1023 atoms; the molecule of nitrogen is diatomic.
Since quinine has a nitrogen atom in its chemical formula, 1 mole of quinine contains 1 mole of nitrogen atoms. Therefore, in 2.5 x 10^-2 moles of quinine, there are also 2.5 x 10^-2 moles of nitrogen atoms.
3 x 12 = 36 moles of Nitrogen atoms N or 18 moles of Nitrogen molecules N2
1.38 moles of nitrogen equal16,62110876532.1023 atoms; the molecule of nitrogen is diatomic.
yes it contains two moles of nitrogen because NH4NO3 has two nitrogen therefore it equals to 2 moles on nitrogen.
At standard temperature and pressure, nitrogen exists as diatomic molecules. Therefore the number of atoms in 3.4 moles is 2 X 3.4 X Avogadro's Number, or 4.1 X 1024 atoms, to the justified number of significant digits.

There are 3 moles of nitrogen in 3 moles of ammonium nitrate. Ammonium nitrate contains 2 nitrogen atoms in its chemical formula NH4NO3. Each mole of ammonium nitrate contains 2 moles of nitrogen atoms.
There are 4.81 x 10^23 atoms of nitrogen in 2.50 moles of NO2. This is because each molecule of NO2 contains 1 atom of nitrogen.
There are approximately 3.01 moles of urea in 25 g of CONH2, so there are 3.01 moles of nitrogen atoms. Therefore, there are 3.01 moles * 2 nitrogen atoms/molecule = 6.02 moles of nitrogen atoms in 25 g of CONH2, or urea.
The answer is 24,92 g nitrogen.
