Question

what is the concentration for 100 g of naoh in 250 ml solution

Answer 1

we can find concentration in different ways. for this particular question we have to find the molarity of the solution.
molarity=no. of moles/volume
           =weight/molecular weight *1/volume(lit)               (molecular weight of                                                                                           NaOH=23+16+1=40)
           =weight/molecular weight *1000/volume(ml)
           =0.1/40 *1000/250
           =1 molar
