The total amount of gas present in the container of 1 L is 0.0446 moles and in container of 3 L is 0.1334 moles.
Explanation:
It is known that 1 mole of any gaseous element contains 22.4 litres of that gas molecules. So in order to determine the total amount of gas present in 1 L and 3 L, we can divide the given volume with the reciprocal of 22.4 litre to determine the moles of gas at 1 L and 3 L respectively.
So for 1 L
So no. of moles in 1 L = 0.0446 moles of that gas is present in 1 L volume.
Similarly, total amount of gas present in 3 L is
No. of moles present in 3 L =
So, the total amount of gas present in 1 L is 0.0446 moles and in 3 L is 0.1334 moles. Thus, it can be stated that the number of moles increases with increase in the volume or on expansion of gas molecules.

Explanation:
Hello!
In this case, when writing chemical reactions from the given names we must make sure we know the proper formula for each reacted and produced species; thus, since solid iron (III) oxide is , hydrogen gas is
, solid iron is Fe and liquid water is just
, we can write:
However, since different amount of atoms of iron, hydrogen and oxygen are present at each side of the equation, we balance it by adding the following coefficients to each molecule:
And now it is balanced with two iron atoms, three oxygen atoms and six hydrogen atoms at both reactants and products.
