Question

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?

No, because they have different masses.
No, because they have different volumes.
Yes, because the number of moles is not dependent on the mass or the volume.
Yes, because the number of moles is only dependent on the mass per unit volume.

Answer 1

Yes, because the number of moles is not dependent on the mass or the volume.
Different elements and compounds have different molar masses. E.g. a mole of hydrogen would be very different from a mole of gold

Answer 2

Answer: Yes, it is possible for each samples to contain 1 mole of a substance because the number of moles are not dependent on the mass or the volume.

Explanation:

The formula for the number of moles is given by:

`\text{number of moles}=\frac{\text{given mass}}{\text{molar mass}}`

As, the masses of 2 samples are different, so the number of moles will be dependent only on the molar masses of the samples.

Volume has no effect on the number of moles.
