this is based on conecpt of molarity                                                                                             molarity = mole of solvent /volume of solution in L                                        here,                                                                                                                       molarity of solution=2M                                                                                         volume of solution =250m

hence,                                                                                                                             2M =mole of NaOH/[250 /1000]

mole of NaOH=0.5

weight in gram = 0.5 *40 gram =20 gram
