How many atoms of Fe are in 12.5 g Fe?
To determine the number of atoms in 12.5 g of Fe, you need to first calculate the number of moles of Fe using its molar mass (55.84 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.

How many iron atoms are contained in 354 g of iron?
There are approximately 3.25 x 10^24 iron atoms in 354 g of iron. This calculation is done by converting the mass of iron to moles using the molar mass of iron, and then using Avogadro's number to convert moles to atoms.
Which one has more no of atoms 10 g of Al or 10 g of Fe?
10 g of Fe has more atoms because iron has a lower atomic mass than aluminum. This means that there are more atoms in 10 g of Fe compared to 10 g of Al.

How many pages does 'G' Is for Gumshoe have?
'G' Is for Gumshoe has 261 pages.
Which has more atoms 3.0 grams of iron Fe or 2.0 grams of sulfur?
3.0 g Fe x 1 mole Fe/55.8 g = 0.054 moles Fe2.0 g S x 1 mole S/32 g = 0.063 moles STherefore there are more molecules of S than of Fe since one mole of either = 6.02x10^23 atoms.
How many moles of nitrogen atoms are present in 53.55 g of FeNO32?
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
