The mass number of the isotope uranium-234 is 142.
Uranium is a non metal element. Atomic mass of it is 238.
the atomic mass number for uranium is 92
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
Uranium atomic number: 92 Uranium atomic weight: 238,02891 Uranium number of protons: 92
To find the number of moles of uranium in 3 cubic centimeters, you would need to know the density of uranium. Once you know the density, you can calculate the mass of 3 cubic centimeters of uranium and then use the molar mass of uranium to convert the mass to moles. The number of moles can be calculated using the formula: moles = mass (g) / molar mass (g/mol).
The atomic weight of uranium is 238,02891.
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
The atomic weight of uranium is 238,02891(3) atomic mass units.
The most common isotope of uranium is uranium-238 with 146 neutrons.
Uranium isotopes have 92 protons and electrons; the number of neutrons is different for each isotope.Number of neutrons = Mass number - Number of protons
To find the number of uranium atoms in 6g of pure uranium, we first need to calculate the molar mass of uranium, which is approximately 238.03 g/mol. Then, we use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the mass to number of atoms. So, 6g of uranium contains about 6.022 × 10^23 atoms.
