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?

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

Answer 1

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?

C) Yes, because the number of moles is not dependent on the mass or the volume.

Answer 2

Answer: The correct answer is Option C.

Explanation:

To calculate the number of moles, we use the formula:

`\text{number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}`

We are given in the question that the masses of twp samples are different and from the above formula, we see that the moles of a substance depends on the molar masses of the substance.

Volume of the substance has no effect on the moles.

So, the two substances can have 1 mol of substance.
