Particles in a solid state can only vibrate. In a liquid state, they slide against each other. And in a gas state, they move freely, bouncing and bumping into each other.
The number of moles of nitrogen gas is 1.0 mole
<u><em>calculation</em></u>
N2 is a molecule therefore;
1 molecule of N₂ = 2 atoms of N
? molecules= 1.2 x10 ²⁴atoms
<em>by cross multiplication</em>
=[( 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
<em>by cross multiplication</em>
= [(6.0x 10²³ molecules x 1 mole) / 6.02 x10²³ molecules] = 1.0 mole
