Answer:
Option A = 2.2 L
Explanation:
Given data:
volume of one mole of gas = 22.4 L
Volume of 0.1 mole of gas at same condition = ?
Solution:
It is known that one mole of gas at STP occupy 22.4 L volume. The standard temperature is 273.15 K and standard pressure is 1 atm.
For 0.1 mole of methane.
0.1/1 × 22.4 = 2.24 L
0.1 mole of methane occupy 2.24 L volume.

The unbalanced equation is:
Fe(s) + O2(g) —> Fe2O3(s)
To balance oxygens, multiply O2 by 3 and Fe2O3 by 2.
Fe(s) + 3O2(g) —> 2Fe2O3(s)
Balance your iron by multiplying Fe by 4, since you have 4 Fe in the products now.
4Fe(s) + 3O2(g) —> 2Fe2O3(s)
