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 :
[tex]\tt 2\times 0.755=1.51~moles[/tex]
The number of atoms N :
[tex]\tt 1.51\times 6.02\times 10^{23}=9.09\times 10^{23}~atoms[/tex]
