Question

Helium gas consists of single atom.what mass of helium contains 6.022×10^23 atoms?

Answer 1

hi friend
here is your answer

this is good question to ask that is related to mole concept.

as the Helium atom has the mass of 4 amu

so according to the mole concept 6.022×10^23 atoms is contained in a one mole.

so we can say that a one mole of Helium atom has a mass of 4 gram.

or 6.022×10^23 atom has a mass of 4 grams.

hope it is helpful for you so please mark my answer as brainliest.

Answer 2

Hey there,

Avogadro number=6.022*10²³

Mass of helium=4 amu

Moles=Given mass/Atomic mass

Since it is given that there are 1 mole,

So 1=x/4

=> 4 grams of Helium has 1 mole.
