Question

How many atoms of N are in 0.755 mol of N2? ( mole conversion)

Answer 1

The number of atoms N in 0.755 mol of N₂ : 9.09 x 10²³

Further explanation

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 of N in 0.755 mol N₂ :

`\tt 2* 0.755=1.51~moles`

The number of atoms N :

`\tt 1.51* 6.02* 10^(23)=9.09* 10^(23)~atoms`
