Answer #1

10% w/w of NaOH means 10g of NaOH present in 100g of solution

weight of solvent = weight of solution - weight of solute

                              = 100-10 = 90g

molality = W*1000/G.M.Wt* weight of solvent in g

              = 10*1000/40*90   = 2.78m >>>>>answer

What is the mole fraction, X, of solute and the molality, m (or b), for an aqueous solution that is 19.0% NaOH by mass? hint: Molality, m (or b), is the number of moles of solute per kilogram of solvent. Mole fraction, X, is the number of moles of a component divided by the total number of moles. Choose an arbitrary mass of solution, such as 100 g, and determine the masses of NaOH and H2O. Then convert those values...
