Depends on the isotope. Most uranium found naturally is U238 and hence 238 g would be 1 mole. U235 used for fission and bombs would be 235g.
1 mole of uranium is equivalent to 238,02891 grams.
The mass of an uranium-238 atom is 238,0507882/6,022 141 79 × 1023 g.
depends on the isotope - for U238 it would be 1/238 = 0.0042

For the isotope plutonium-239: cca. 2,52.1021atoms.
It depends on the atomic mass of a substance. To find out, divide the 1 by the atomic mass of the element (found on the periodic table), then multiply by 6.02*1023. Ag=(1/Am)*6.02*1023 Where Am=atomic mass of the element, and Ag=the number of atoms in a gram.
1 gram phosphorus (1mol P/30.97 grams)(6.022 X 10^23/1mol P) = 1.9 X 10^22 atoms of phosphorus
1 mole S atoms = 32.065 g S (atomic weight in grams) 1 mole S atoms = 6.022 x 1023 atoms S (Avogadro's number) Convert atoms to moles. 2.01 x 1022 atoms S x (1mol S/6.022 x 1023 atoms S) = 0.0334mol S Convert moles to mass in grams. 0.334mol S x (32.065g S/1mol S) = 10.7g S
1 gram molybdenum (1 mole Mo/95.94 grams)(6.022 X 1023/1 mole Mo) = 6 X 1021 atoms of molybdenum ========================
1 nanogram of natural uranium = 2,53.1012 atoms
There are 15.432 grains in one gram224 grains=1 dwt / 1 { pennyweight } =.05 troy ounce / 1 gram=.643 pennyweight / 1 grain = 0.0648 grams / 4 grains = 1 carat / 15.432 grains = 1 Gram
1 atom-gram of uranium = 238,02891 grams
I won't even waste the time looking up actual numbers.a mole of atoms of helium is about 4 grams, therefor 1 gram of helium is about 0.25 moles of helium atomsa mole of atoms of uranium is about 238 grams, therefor 1 gram of uranium is about 0.0042 moles of uranium atomsA gram of helium contains more atoms than a gram of uranium by about a factor of 60.
1 atom gram of natural uranium = 238,028 91 grams
9.6 grams of uranium (1 mole U/238.0 grams)(6.022 X 10^23/1 mole U) = 2.4 X 10^22 atoms of uranium

1. Uranium contain atoms, not molecules. 2. Many chemical compounds contain in the molecule uranium: uranium dioxide, uranium tetrafluoride, uranyl nitrate, etc.
3.58 X 1024 atoms of uranium (1 mole U/6.022 X 1023) = 5.94 moles uranium to be precise and with significant figures -------------------------------------------------------------------------------
The answer is 4,745.10e21 atoms.
1 gram = 1000 mg
For the isotope plutonium-239: cca. 2,52.1021atoms.
