A. Beran 2022-08-16 The leading lab manual for general The empirical formula for the compound containing uranium and fluorine is "UF"_6". So, Molar mass of Uranium hexafluoride (UF6) = Molar mass of 1 Uranium (U) atom + Molar mass of 6 Fluorine (F) atoms.= 238.03 + (18.998) 6= 238.03 + 113.988= 352.018 g/mol. "This is really helping a lot. [15][16] Storage cylinders must be regularly inspected for signs of corrosion and leaks. Oxygen (O) being 16*1=16. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. 352 g/mol x 1.369*10^-4 mols = ?? 8) UF6. We separate U-235 from U-238 by fluorinating a sample of uranium to form UF6 (which is a gas) and then taking advantage of the different rates of effusion and diffusion for compounds containing the two isotopes. Oxidation with fluorine yields UF6. Both uranium atoms have 92 protons; 238U atoms have 146 neutrons and 235U atoms have 3 less. So lets look at the molar mass of Uranium and Fluorine from the above periodic table. The estimated lifetime of the steel cylinders is measured in decades. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Uranium enrichment produces large quantities of depleted uranium hexafluoride, or DUF6, as a waste product. However, some elements, such as hydrogen, nitrogen, and oxygen, only occur naturally in molecules of 2 or more atoms. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. First, youll need to find the chemical formula for the compound. [18] The U.S. government has been converting DUF6 to solid uranium oxides for disposal. Find Atomic Mass of Each Element Next, using the periodic table, find the atomic mass in g/mol of each element: Thus, \[\begin{align} u_{\rm rms} &= \sqrt{\dfrac{3RT}{M}} \\[4pt] &=\rm\sqrt{\dfrac{3\times8.3145\;\dfrac{J}{K\cdot mol}\times(20+273)\;K}{56.11\times10^{-3}\;kg}}\\[4pt] &=361\;m/s \end{align} \nonumber \]. Multiply those numbers together for the answer. Uranium hexafluoride is a volatile white solid that reacts with water, releasing corrosive hydrofluoric acid. What is the molecular mass of oxygen and hydrogen as a mixture? Calculate the molar masses of the following chemicals: 1) Cl2. a) CH4 b) CO2 c) UF6 molar mass of CH4 = 16 g molar mass of CO2 = 44 g molar mass of UF6 = 352 g 1 mole CH4 1 mole CO2 1 mole UF6 Density of CH4 = (16 g ) 1 mole CH4 x ( 1 mole CH4) = 0.71384 g/L 22.414 L molar mass of CO2 = (44 g) x (1 mole CO2) 1 mole CO2 22.414L molar mass of UF6 = (352 g) 1 mole UF6 14. x ( 1 mole UF6) 22.414 L = 1.9631 g/L = To work with meaningful amounts of substances, scientists group them into units called moles. The molar mass and molecular weight of UF. By using this service, some information may be shared with YouTube. In contrast, rubber balloons filled with air tend to retain their shape and volume for a much longer time. Only 235-U is. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. Flourine reacts with uranium to produce uranium hexafluoride ( UF 6) as represented by this equation: U(S)+3F 2(g)UF 6(g) Number of fluorine molecules required to produce 7.04 mg of uranium hexafluoride ( UF 6) from an excess of uranium is : (Molar mass of UF 6 is 352 g/mol and N A=610 23) A 3.610 19 B 3.610 15 C 4.610 19 D 4.610 15 Medium Join / Login. Dont forget to take into account the number of atoms of each element when you make your calculation. You can also ask for help in our chat or forums.

One mnemonic device for remembering diatomic elements (molecules of 2 atoms) is: Have No Fear Of Ice Cold Beverages (Hydrogen, Nitrogen, Fluorine, Oxygen, Iodine, Chlorine, Bromine). For most elements, this means that the relative atomic mass is equal to the molar mass. Question: One step in the separation of isotopes of uranium is to convert the oxide or uranium to uranium hexafluoride, UF6. The denser the gas, the shorter the mean free path; conversely, as density decreases, the mean free path becomes longer because collisions occur less frequently. Example Reactions: U + 3 F2 = UF6 UF4 + F2 = UF6 UF6 + 2 H2O = UF2O2 + 4 HF UO4 + 3 F2 = UF6 + 2 O2 UF6 + 3 Mg = 3 MgF2 + U UF6 + 2 H2O = UO2F2 + 4 .

Some fission products form nonvolatile fluorides which remain as solids and can then either be prepared for storage as nuclear waste or further processed either by solvation-based methods or electrochemically. She received her MA in Environmental Science and Management from the University of California, Santa Barbara in 2016.
