The reason why aiming for
Answer to Problem 4RQ
It is impractical to have a
Explanation of Solution
If a sample contains only one element or compound, it is known to be pure. Otherwise, the sample is impure.
The macroscopic sample is made up of a large number of molecules (trillions). The molecules are of a very small size.
It is impractical to check for each atom to be of the same element.
So,
Conclusion:
Therefore, it is impractical to have a
