A mole of the element U (uranium) and a mole of CO2:

have the same molecular weight
have the same atomic mass
have an equal number of particles
have an equal number of atoms

Respuesta :

Answer: The correct answer is they have same number of particles.

Explanation:

According to mole concept:

1 mole of an element or compound contains [tex]6.022\times 10^{23}[/tex]  number of particles.

The number is known as Avogadro's number.

We are given:

One mole of uranium element and 1 mole of carbon dioxide molecule.

These two substances have same number of particles equal to Avogadro's number.

Hence, the correct answer is they have same number of particles.
