Answer:

320 g.

Explanation:

The formula of iron oxide is Fe₂O₃.

  • 1 mole of a compound contains a mass equivalent to the relative formula mass of that particular compound.
  • Atomic mass of Iron = 56 , while that of oxygen is 16.

  • Total mass of the compound will be = (56 ×2) + (16 ×3)

                                                            = 112 + 48

                                                            = 160

  • For 2 mole of the compound i.e 2 Fe₂O₃ the mass will be = 160 × 2

                                                                                                         =320 g.

Result: 2 mole of Iron oxide has a mass of 320 g.
