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

How many atoms are in 0.5 mole of Ar?
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
How many Kr atoms are there in 2.51 moles of Kr?
The number of atoms is 15,11.10EX23.
Does a sample of glucose C6H12O6 contain 1.261e21 atoms of carbon?
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.
How many moles of fluorine atoms are in a sample of fluorine that contains 7.45 x 1024 fluorine atoms?
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

How many nitrogen atoms would be present in 7 moles of NH42C2O4?
Your compound's chemical formula is (NH4)2Cr2O7 - so you can see that it contains 2 moles of NH4+ per mole of the salt. So in 7 moles you have 14 moles of ammonium, containing 14 moles of N atoms which means that you have (1 mole = 6,022*10^23 atoms) 14 mols * 6,022*10^23 atoms/mole = 8,43*10^23 atoms
