What are the molar masses of uranium 238 and uranium 235?
U-238 and U-235 are the two isotopes of Uranium. Molar mass M is not the right expression for each isotope. The naturally occurring Uranium has the following composition : 0.7% U-235, its Atomic Mass is 235.043 amu (amu is atomic mass unit), and. 99.3% U-238, its atomic mass is 238.05 amu.
What is the molar mass of uranium -238?
238 grams/mole The isotopic number is the approximate mass for any element. Such as if I say Carbon 14, the approximate mass is 14 grams/mole. If you are asking what is the mass of one atom of Uranium 238: Then you take the isotopic mass 238 grams/mole and divide by Avogadro's Number 6.022X10^23 atoms/mole this gives you units of grams/atom.
What are the molar masses of uranium -238 and uranium -235?
U-238 and U-235 are the two isotopes of Uranium. Molar mass M is not the right expression for each isotope. The naturally occurring Uranium has the following composition : 0.7% U-235, its atomic mass is 235.043 amu (amu is atomic mass unit), and. 99.3% U-238, its atomic mass is 238.05 amu.
What is the mass in grams of 1.92 moles of uranium atoms What if your answer?
To find the mass of 1.92 moles of uranium atoms, you can use the molar mass of uranium, which is approximately 238 grams per mole. Multiply the number of moles by the molar mass: 1.92 moles × 238 g/mole = 456.96 grams. Therefore, the mass of 1.92 moles of uranium atoms is about 457 grams.
What is the mass in gram of 0.500 mole of uranium?
The mass of o,5 mole of uranium is 119,014455 g.
Why 23 g of sodium and 238 g of uranium have equal number of atoms?
The number of atoms in a given mass of a substance can be determined using the molar mass. Sodium has a molar mass of approximately 23 g/mol, while uranium has a molar mass of about 238 g/mol. Therefore, 23 g of sodium corresponds to 1 mole (or approximately (6.022 \times 10^{23}) atoms), while 238 g of uranium also corresponds to 1 mole. This means that both quantities contain the same number of atoms, despite their differing masses.
What is the mass number of urnanium?
Uranium is a non metal element. Atomic mass of it is 238.
How much faster does UF 235 effuse compared with UF 238?
Uranium-235 (UF₃₅) effuses faster than uranium-238 (UF₂₃₈) because of its lower molecular weight. According to Graham's law of effusion, the rate of effusion is inversely proportional to the square root of the molar mass. Since UF₃₅ has a molar mass of approximately 235 g/mol and UF₂₃₈ has a molar mass of about 238 g/mol, UF₃₅ effuses roughly 1.01 times faster than UF₂₃₈.
What is the molar mass of one mole of Uranium?
1 atomgram of uranium = 238,02891 gramsAnswer:The molar mass of Uranium is 238.03 g/mol
What is the mass number for the element uranium?
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
How is the structure of an atom or uranium 235 dfferent to the structure of an atom of uranium 238?
The main difference between uranium-235 and uranium-238 is their atomic masses. Uranium-235 has 235 atomic mass units (AMU) while uranium-238 has 238 AMU. This difference in mass is due to the number of neutrons in the nucleus of each isotope.
What do the '238' in uranium-238 and the '14' in carbon-14 mean?
The numbers in uranium-238 and carbon-14 refer to the atomic mass of the isotopes. The number '238' indicates that uranium-238 has a total of 238 protons and neutrons in its nucleus, while the number '14' indicates that carbon-14 has a total of 14 protons and neutrons.
