As discussed in

Molarity -

 Molarity (M) = (Number of moles of solute)/(volume of solution in litres)

 

- wherein

It is defined as the number of moles of the solute in 1 litre of the solution.

 

  Molarity=\frac{n}{v}

=> n=0.5M\times 2l

=> 1.0

That means 1litre solution we have 0.5 mole of naoh                                                                    so for 2litre solution we get                       

2×0.5=1mole of naoh
