B.

The jar of sulfur.

Explanation:

The molar mass of sulfur is 32 g/mol

The molar mass of Aluminium is 27g/mol

The molar mass of carbon is 12 g/mol

Therefore based on these numbers, it is evident that a mole of Sulfur weighs the heaviest.

Different elements weight different because their atoms have different mass numbers. The lower you go in the periodic table the heavier the atoms became because they have more atomic units (neutrons and protons) in their nuclei.

The atomic mass of Sulfur has been the highest. Thus, the mass of 1 mole of Sulfur is high as compared to others. So, option B is correct.

The atomic mass has been equal to the mass of an element in 1 mole.

From the given atomic mass, the masses are:

Carbon: 12 g/mole

Sulfur: 32 g/mole

Aluminum: 27 g/mole

  • Since each jar contains 1 mole of the element, and the mass in 1 mole is different. Each jar does not contain the same mass. Thus option D is incorrect.

From carbon, sulfur, and aluminum, the highest atomic mass is of sulfur. The increasing order of atomic mass will be :

Carbon < Aluminum < Sulfur.

  • Since carbon element has the lowest atomic mass, option A is incorrect.

  • The atomic mass of aluminum lies in between carbon and sulfur. The atomic mass of Aluminum is not the highest. Thus, option C is incorrect.

  • The atomic mass of Sulfur has been the highest. Thus, the mass of 1 mole of Sulfur is high as compared to others. So, option B is correct.
