How are 2 mole NaOH and 2 Molar NaOH different?

Explanation

2 mole NaOH
1 mole of NaoH `=40g` of NaOH `=6.023xx10^(22)` molecules
2 mole of NaOH `2xx40g=80g` of NaOH
`=2xx6.023xx10^(23)` molecules.
2 molar NaOH
1 molar `NaOH=40g` of NaOH in 1000 ml of water
2 molar NaOH `=80g` of NaOH in 100 ml of water
`=2` moles of NaOH dissolved in 1000 ml of its solution.
