Question:
$80\,g$ of oxygen contains as many atoms as in
$80\,g$ of oxygen contains as many atoms as in
Updated On: Apr 2, 2024
- $80\,g$ of hydrogen
- $1\,g$ of hydrogen
- $10\,g$ of hydrogen
- $5\,g$ of hydrogen
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Number of moles of oxygen $=\frac{80}{16}$
Number of atoms of oxygen $=\frac{80}{16} \times N_{0} \times 2$
$=5 \times N_{0} \times 2$
Number of moles of $5 \,g$ of hydrogen $=\frac{5}{1}$
Number of atoms in $5 \,g$ of hydrogen $=5 \times N_{0} \times 2$
Hence, the number of atoms in $80 \,g$ of oxygen is equal to the number of atoms in $5\, g$ of hydrogen.
Number of atoms of oxygen $=\frac{80}{16} \times N_{0} \times 2$
$=5 \times N_{0} \times 2$
Number of moles of $5 \,g$ of hydrogen $=\frac{5}{1}$
Number of atoms in $5 \,g$ of hydrogen $=5 \times N_{0} \times 2$
Hence, the number of atoms in $80 \,g$ of oxygen is equal to the number of atoms in $5\, g$ of hydrogen.

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.
