Answer:
Mass of 2 moles of \(^{238}\textrm{U}\) is 476.1 g
Explanation:
- We know that number of moles of an atom is ratio of mass of the atom to it's atomic weight.
- Atomic weight of \(^{238}\textrm{U}\) is 238.05 g/mol
- So, mass of 1 mol of \(^{238}\textrm{U}\) atom is 238.05 g
- Hence mass of 2 moles of \(^{238}\textrm{U}\) = \((2mol\times 238.05g/mol)=476.1 g\)
- Hence mass of 2 moles of \(^{238}\textrm{U}\) is 476.1 g
