(Solved): how many grams of Fe2O3 can form from 20.9g of O2? 1.show the strategy for solving this problem ...

How many grams of \( \mathrm{Fe}_{2} \mathrm{O}_{3} \) can form from \( 20.9 \mathrm{~g} \mathrm{of} \mathrm{O}_{2} \) ? \[ 4 \mathrm{Fe}(\mathrm{s})+3 \mathrm{O}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s}) \] Step 1: Show the strategy for solving this problem. Step 2: Show the conversions required to solve this problem and calculate the grams of \( \mathrm{Fe}_{2} \mathrm{O}_{3} \). grams of \( \mathrm{Fe}_{2} \mathrm{O}_{3} \) :
