The number of moles of nitrogen gas is 1.0 mole
calculation
N2 is a molecule therefore;
1 molecule of N₂ = 2 atoms of N
? molecules= 1.2 x10 ²⁴atoms
by cross multiplication
=[( 1.2 x 10²⁴ atoms x 1 molecule) / 2 atoms] = 6 x 10²³ molecules
According to Avogadro's law 1 mole =6.02 x 10²³ molecules
? moles= 6.0 x 10²³ molecules
by cross multiplication
= [(6.0x 10²³ molecules x 1 mole) / 6.02 x10²³ molecules] = 1.0 mole
