Question

give reason that 1 mole of different compounds have different masses but have the same number of molecules.​

Answer 1

Answer:

Because a mole of anything is a fixed quantity.

Explanation:

Mole or Avogadro's Constant is a unit for measuring particles.

1 mole=6.022×10²³ no. of atoms/molecules etc.

The explanation for your question is the same as that why 1 kg of everything has the same quantity of matter.

Hope it helps.

Answer 2

Answer:

1 mole of different compounds have different masses but have the same number of molecules because:

Explanation:

1 mole of any substance = 6.02214086 × 10²³ atoms, molecules or formula                                                                                                                                                                 units

The above expression tells about Avagadro's constant related to moles.
