Answer:
320 g.
Step-by-step 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.
