use this formula mass = moles x molar mass

Answer:

Mass of 2 moles of [tex]^{238}\textrm{U}[/tex] 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 [tex]^{238}\textrm{U}[/tex] is 238.05 g/mol
  • So, mass of 1 mol of [tex]^{238}\textrm{U}[/tex] atom is 238.05 g
  • Hence mass of 2 moles of [tex]^{238}\textrm{U}[/tex] = [tex](2mol\times 238.05g/mol)=476.1 g[/tex]
  • Hence mass of 2 moles of [tex]^{238}\textrm{U}[/tex] is 476.1 g
