A mole is a unit of measurement that is used to measure the number of things. The amount of moles that are in 4.3 x 1021 molecules of UF6 are 9.34 and the amount of grams is 2.51.
UF6 is uranium hexafluoride.
uf6 + 2 h2o= uo2f2 + 4 hf
This compound is UF6. Atomic weight of uranium: 238,02891 Atomic weight of fluorine: 18,9984032 Molecular mass of UF6: ca. 352,04121
It is a strong reaction between UF6 and H2O: UF6 + H2O ------- UO2F2 + HF
U3O8 + HNO3 yields UNO3 + H2 yields UO2 + HF yields UF4 + F2 yields UF6
The chemical formula of uranium hexafluoride is UF6.
.071 moles
