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.
There is NO element with the Atomic No. of 238. Atomic No. only go to ~ 110. However, There is an element with ATOMIC MASS of 238, it is an isotope of Uranium NB . Atomic Number refers to #1 the position in the periodic table #2 the number of protons in the element #3 the number of electrons in the neutrally charged element. Atmoic Mass refers to the Sum total of all the protons and neutrons in the nucleus of an element. An element such as Uranium would be shown in the periodic table as [238/92]U. The two numbers indicating the Atomic Mass and the Atomic Number.
Uranium-238 and uranium-234 are not "elements", but they are natural isotopes of the chemical element uranium. The atoms are neutral.
Uranium-235 and uranium-238 are the isotopes of the same element - uranium, a natural radioactive chemical element; the atomic number is the same - 92. Also the electronic structure, the number of protons, etc. Differences: atomic mass, number of neutrons, U-235 is fissile with thermal neutrons but U-238 is only fertile, halflife, type of disintegration types and energy of emitted radiations, etc.
Uranium-238 is a natural isotope of uranium with the mass 238,050 788 247 ± 0,000 002 044 u.a.

what is the atomic mass of an element : atomic mass is equal to the number of protons and number of neutrons present in an element
Pure Uranium-238 has an Atomic Mass of 238.1252 amu. Thus one mole of it weighs 238.1252 grams.
Uranium is a non metal element. Atomic mass of it is 238.
The atomic mass number of that isotope. So C14 has a molecular mass of 14 grams/mole U238, 238 grams/mole
There is NO element with the Atomic No. of 238. Atomic No. only go to ~ 110. However, There is an element with ATOMIC MASS of 238, it is an isotope of Uranium NB . Atomic Number refers to #1 the position in the periodic table #2 the number of protons in the element #3 the number of electrons in the neutrally charged element. Atmoic Mass refers to the Sum total of all the protons and neutrons in the nucleus of an element. An element such as Uranium would be shown in the periodic table as [238/92]U. The two numbers indicating the Atomic Mass and the Atomic Number.
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
The atomic mass of uranium 238 is 238,050 788 247
U-238 is not fissionable.
* 238 is the atomic mass of a natural uranium isotope. * 14 is the atomic mass of a carbon isotope.
The heaviest (hevest?) naturally occurring element is Uranium (238 a.m.u.) but the heaviest known element is atom number 114, 117 or 118, the exact mass being unknown but over 250.
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.
