Which of the following quantites would have the greatest mass: one mole of carbon atoms, one mole of helium atoms, one mole of neon atoms?

A) one mole of helium atoms

B) one mole of carbon atoms

C) They would have equal masses.

D) one mole of neon atoms

Respuesta :

Atomic mass of carbon is 12 so 1 mole = 12 grams.

For helium it is 4.003 grams

For neon it is 20.18 grams

So one mole of neon has the greatest mass.

The mass of 1 mole of neon is greater than 1 mole of carbon or helium. Option  D is correct.

What is the Mole concept?

  • The mole is a constant that is used as a unit to measure the small particles such as the atom, ion, and molecules.

  • 1 mole is equal to the Avogadro's constant [tex]6.02 \times 10^2^3[/tex]

[tex]n = \dfrac wm[/tex]

Where,

[tex]n[/tex] - number of moles

[tex]w[/tex] - weight (given mass)

[tex]m[/tex] - molar mass

For Carbon,

[tex]1 {\rm \ mole} = \dfrac w {12}\\\\w = 12[/tex]

So, the 1 mole of Carbon has 12 g of mass.

1 mole of Helium has about 4 g of mass.

1 mole of neon has about 20 g of mass.

Therefore, the mass of 1 mole of neon is greater than 1 mole of carbon or helium.
