One gram mole of a gas at NTP occupies $22.4\, L$. This fact was derived from
One gram mole of a gas at NTP occupies $22.4\, L$. This fact was derived from
Updated On: Jun 23, 2023
- law of gaseous volumes
- Avogadro's hypothesis
- Berzelius hypothesis
- Dalton's atomic theory
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
According to ideal gas equation, $P V=n R T$
Putting the standard conditions,
i.e. $P =1$ atm $n=1$ mole,
$R=0.0821\, L$ atm $K^{-1}$, mol $^{-1},$
$T=273\, K$
$V=\frac{n R T}{P}=\frac{1 \text { mole } \times 0.0821 L\,atm K^{-1} mol ^{-1} \times 273\, K }{1 atm }$
$V=22.4$

Some Basic Concepts of Chemistry
Chemistry is a vast subject and for understanding its significance we can take help of following points:
- Chemistry plays an important role in understanding various subjects like physics, geology and biology.
- Chemistry is a core branch of science that explains us about the various compositional properties and interaction of matter. It also helps to understand various chemical reactions.
- Chemistry is important in order to understand the behaviour of fertilizers, alkenes, acids, salts, dyes, polymers, drugs, soaps and alloys in organic and inorganic chemistry.
- Chemistry plays an important role in various fields like healthcare, industrial, research, food, and farm activities.

Classification of Matter
There are two ways of classifying the matter:
(A) Physical Classification:
Matter can exist in three physical states:
- Solids - have definite volume and definite shape
- Liquids - have definite volume but not definite shape.
- Gases - have neither definite volume nor definite shape.
(B) Chemical Classification:
Based upon the composition, matter can be divided into two main types:
- Pure Substances are defined as a single substance (or matter) which cannot be separated by simple physical methods. Pure substances can be further classified as (i) Elements (ii) Compounds
- Mixtures are the combination of two or more elements or compounds which are not chemically combined together and may also be present in any proportion.
