Weight of NaOH = 25 g
 
No. of moles =25/40
 
                   = 0.625 mole
 
Volume = 50 ml
 
           = 0.05 litre
 
 
Molarity space equals fraction numerator No. space of space moles space of space solute over denominator Volume space in space litre end fraction

space space space space space space space space space space space space space equals fraction numerator 0.625 over denominator 0.05 end fraction

space space space space space space space space space space space space space space equals space 12.5 space straight M
 
Molarity = 12.5 M of NaOH.
