1.	Calculate the morality of NaOH when its 20gm dissolved in 500 ml water.1 1M2.5M3 100 M410 M
Answer» The molecular WEIGHT of NaOH is 40 g/mol.The NUMBER of moles of NaOH 40 g/mol5 g =0.125 moles.500 ml water corresponds to0.500 L.The MOLARITY of the solution = 0.500 L0.125 moles =0.25 M.I hope its RIGHT .EXPLANATION:I
