Answer:
Fe_2O_3
= 0.2128 x
Weight of the rust,
\frac{0.2128 x}{159.7 g/mol}
Moles of rust =
1 mole of rust has 2 moles of iron.
2\times \frac{0.2128 x}{159.7 g/mol}
Moles of iron in rust =
2\times \frac{0.2128 x}{159.7 g/mol}\times 55.85 g/mol=0.1488 x
Weight of moles of iron:
Weight of iron calculated above is the iron which has been present in the form of rust on iron.
Percent of iron that has been rusted:
\frac{0.1488 x}{x}\times 100=14.88\%
14.88% of iron has been rusted
