No, uranium hasn't the biggest atomic weight. Also the density of uranium is not the biggest.
Plutonium generally has a lower atomic mass compared to uranium because it has fewer protons and neutrons in its nucleus. Plutonium isotopes tend to have a smaller number of nucleons overall compared to most uranium isotopes, resulting in a lower atomic mass.
The most common isotope of uranium is uranium-238 with 146 neutrons.
The atomic mass of the most common isotope of plutonium (Pu-234) is higher than the masses of the uranium natural isotopes.
Atomic weight (not mass) of uranium is 238,02891.
Atomic mass number = Number of protons + Number of neutrons Number of protons of uranium nucleus is 92. The number of neutrons is different for each isotope. Example for 238U: 92 protons + 146 neutrons = 238
The atomic weight (not mass) of uranium is 238,02891(3).The density of uranium is 19,1 g/cm3.
Uranium is a non metal element. Atomic mass of it is 238.
The atomic weight of uranium (not mass) is 238,02891.
To calculate the mass of uranium, we need to know the molar mass of uranium hexafluoride (UF6), which is approximately 352 g/mol. Given that the sample has 175.5 g of UF6, we can calculate the mass of uranium by multiplying the molar mass of uranium by the ratio of the molar mass of uranium to the molar mass of UF6 (238.03 g/mol / 352 g/mol) and then multiplying by the mass of UF6 provided. This would result in approximately 119.196 g of uranium in 175.5 g of UF6.
The mass number of the isotope uranium-234 is 142.
The mass of 10 mole of natural uranium is 2380,2891 g.
1 atomgram of uranium = 238,02891 gramsAnswer:The molar mass of Uranium is 238.03 g/mol
