Question

Calculate the volume in milliers of a 2.6 mol/L sodium chloride solution that contains 100 mmol of sodium chloride (NaCl). Be sure your answer has the correct number of significant digits. mL X 5 ?

Answer 1

Method-I! Concentration of the 'Solution of Nac! is = 2.6 mdli. That means 'one Litre Nacl Solution contains 2.6 moles of Nacl dissolved. le 2.6 moles of Nach is preseest in 11 sdution 2.6 moles of Nach Present in 100 mmol = 100x1ömdes Present in 1 Litre Solution. 2 .: The volume of Nad solution = 1 2.6 moles = (0.1 x 1Libre (2.6) = 0.03846 Litre ... The Volume et Nad Solution that contains 100 mmol (millimotes Nad = 0.03846 L = 38.46 mL = 38.46 millilitres Method I Concentratos of the given Solution = Mdanty = 2.6 moj .: Molanty = Number of moles of Solutè Cie. Naw) 7 Volume of Solulion (in Litre) 2.6 mol = Nsolute Vsolution Ifin = 100 mmol = (100x162 moles Volume of the solution V = ?

Molarity (M) - nsolute solution V solution (in Litre) - (Msolute (100xio mol) (2.6 mollis = 0 ) - Cile) -0.03846 Litre ; Volume of solution = 0.03846 Litre = 38.46 ML = 38.46 mililitres
