Approx. o,24 mol.
Molecules or moles? And in a cubic foot of what? Air?
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 -------------------------------------------------------------------------------
You know the molarity and you know the volume. First off you find the moles. Molarity divided by 1000, multiplied by the volume in cm^3. Then you multiply the moles by the molecular mass of the solute, to get the weight in 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.
2,6.10-8 mol

You cannot convert cm3 to moles. They do not measure the same quantity. Cubic centimeters measure volume (the amount of space an object takes up) and moles measure the amount of a substance. The mole is one of the seven fundamental SI units, whereas cubic centimeters is a derived unit.
Atomic weight of uranium: 238,02891 Density of uranium: approx. 19,1 g/cm3 3 cm3 of U = 57,3 g = 0,24 mol
119 grams of uranium is equivalent to 0,5 moles.
.5 to 2 moles.
The answer is 7,145.10-4 mol.
The formula K2(UO2) 2 (VO4) 2 is the formula of the important uranium mineral carnotite. Percent uranium (not moles) in carnotite: 52,77 %.

1 atom-gram of uranium = 238,02891 grams
780 moles
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 -------------------------------------------------------------------------------
One mole of a substance consists of 6.023 X 1023 number of atoms or molecules. So, 0.896 moles of uranium will have 5.396608 X 1023 atoms.
