Explanation / Answer

Which of the following is always true?

One mole of sodium atoms has the same density as one mole of copper atoms. [False]

Because density= mass/Voulme, mass is different for both atoms (Considering one mole), so is the volume and thus the ratio differs, thus it is not true.

One mole of lithium atoms has the same number of protons as one mole of chlorine atoms. [False]

Number of protons = Atomic number of an element, and we know that atomic number is unique for each element, thus this statement is false too.

One mole of hydrogen atoms has the same number of atoms as one mole of sulfur atoms. [True]

One mole of each element has equal number of atoms which is equal to Avagadro
