\(1.82 \times 10^2\; m/s\) (about 410 mi/h). The first step to finding the molar mass is to count the number of each atom present in a single molecule using the chemical formula, UF6: Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element: Finally, add together the total mass of each element to get the molar mass of the molecule: Use uppercase for the first character in the element and lowercase for the second character. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. A gas's root-mean-square speed is determined using the formula: Root-mean-square = 3RT/M Where M is the molar mass of gas in kilograms, T is the temperature, and R is the molar gas constant. Now here we have to find the molar mass of Uranium hexafluoride (UF6). Gas molecules do not diffuse nearly as rapidly as their very high speeds might suggest.

[15][16] Storage cylinders must be regularly inspected for signs of corrosion and leaks. The relationship is based on the postulate that all gases at the same temperature have the same average kinetic energy. When UF 6 is exposed to moist air, it reacts with the water in the air to produce UO 2 F 2 ( uranyl fluoride) and HF ( hydrogen fluoride) both of which are highly corrosive and toxic. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Potassium hydrogen phthalate (KHC8H4O4) Molar Mass, Acetate ion Molar Mass (With Calculations), Periodic table labeled (14 different labeled images), Periodic table with electronegativity values, Protons neutrons and electrons of all elements.

Equation \(\ref{10.8.4}\) shows that Grahams law is a direct consequence of the fact that gaseous molecules at the same temperature have the same average kinetic energy. In 2005, 686,500 tonnes of DUF 6 was housed in 57,122 storage cylinders located near Portsmouth, Ohio; Oak Ridge, Tennessee; and Paducah, Kentucky. In addition to its use in enrichment, uranium hexafluoride has been used in an advanced reprocessing method (fluoride volatility), which was developed in the Czech Republic. Oxidation with fluorine yields UF6. While most relative atomic masses are known to a precision of 1 part in 10 thousand (4 decimal places), in most laboratory work, molar masses are normally quoted to 2 decimal places and fewer for particularly large masses.
