Moles of Helium = 2

Further explanation

Given

12.04 x 10²³ atoms of helium

Required

moles

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

moles Helium :

n = N : No

n = 12.04 x 10²³ : 6.02 x 10²³

n = 2
