Fairly heavy!
1.14 X 1024 atoms of iodine ( 1 mole I/6.022 X 1023)(126.9 grams/1 mole I)
= 240 grams of iodine
-------------------------------
2.11x10^24 atoms... Divide by Avogadro's Constant (6.02x10^23 particles/mole) Gives you moles of copper... Multiply by the molar mass of copper. (?? g/mol) Gives you grams of copper...
The chemical formula is (NO3)-; the mass is 62 g.
Atomic weight of fluorine = 6,022 141 78.1023 (Avogadro number) . 266,889 (the mass of atoms)/8,46.1024 (the number of atoms). The IUPAC 2005 atomic weight of fluorine is 18,998 403 2(5).

1.88 mol Zn ( 6.022 X10^23/1mol Zn ) = 1.13 X10^24 atoms.
Iodine is 127 and Magnesium is 24 so the difference is 103 atomic mass units.
I think you meant 3.09x10^24 atoms of sulfur. 3.09x10^24 atoms * (1 mol / 6.02x10^32 atoms) * (32 g / 1mol) = 165 grams
iodine cells are smaller then glucose ------- I would take exception to the first answer. Iodine is clearly smaller because it exists as a diatomic molecule I2 while glucose is a molecule of 24 atoms, having the chemical formula C6H12O6.
in 1 mol (6.023x10^23) of the substance there would be: 6.023x10^23 atoms of K (potassium) 6.023x10^23 atoms of C (Carbon) 6.023x10^23 atoms of I (Iodine) and 2.408x10^24 atoms of O (Oxygen)

Based on my very little knowledge of chemistry, N and H are both 1 making 2, H4 is 4 hydrogen atoms, CI is a carbon and iodine atom making 2, making 8, so, 8x3=24
1.88 mol Zn ( 6.022 X10^23/1mol Zn ) = 1.13 X10^24 atoms.
To calculate the mass of an atom, 1amu = 1.66*10^-24 and sodium has a mass of 22.99amu. Therefore, 425 sodium atom would be 425*(22.99*(1.66*10^-24))=1.6219445~-20. With the sig fig, the final answer is: 1.62*10^-20g
The number of atoms in a given mass is related to the atomic mass of the element and Avogadro's number, 6.22x1023. If, for instance, we have 18grams of carbon, we divide 18 by the atomic mass of carbon, 12, to get the number of moles, 1.5 (18/12=1.5). Each mole contains 6.22x1023 atoms, so our sample has 1.5mol x 6.22x1023atoms/mole = 9.33x1023 carbon atoms.
