<u>Answer:</u> In accordance to Avogadro's law, two liters of hydrogen gas and one liter of oxygen gas react to form two liters of water.
<u>Explanation:</u>
The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.
Mathematically,
(at constant pressure and temperature)
The chemical equation for the formation of water molecule follows:
The mole ratio of is 2 : 1 : 2
The volume ratio of will also be 2 : 1 : 2
We are given:
Volume of hydrogen gas = 2 L
Volume of oxygen gas = 1 L
Volume of water = 2 L
So, the volume ratio of is 2 : 1 : 2
Hence, in accordance to Avogadro's law, two liters of hydrogen gas and one liter of oxygen gas react to form two liters of water.

- <em>What volume will 12g of iron occupy?</em>
<em></em>
<h2>Solution</h2><em />
<em>Iron</em> is a solid substance at room temperature. You can find the <em>volume</em> of solids (and of not solids) using the density.
You can obtaindthe density of most pure substances in the internet. The density of<em> iron</em> at room temperature is 7.874 g/cm³.
Thus, substituting in the formula, you get:
The answer is rounded to two significant figures because the input, 12g, has two significant figures.
