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.

A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)

it should be p1 v1 = p2 v2
