Chemistry
The pictures below show samples of different substances.
The mass and volume of each sample differ from the mass and volume of the other samples. Is it possible for each sample to contain 1 mol of each substance?
A. No, because they have different masses.
B. No, because they have different volumes.
C. Yes, if each sample contains 6.02 x 1023 atoms.
D. Yes, if each sample contains 2 amu.

C. Yes, if each sample contains 6.02 x 10²³ atoms.
Explanation:
It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.
6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.
If the amount of matter in the given substance is at least one mole, it is possible that they are made up of one mole each of each substance. If they contain lesser amount of atoms, then it is not up to one mole of substance. But if it is greater, then, we can have even more than one mole of substance.A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.
