The content of salt in sweat can be measured by finding the molar concentration of chloride with the use of titration. By analysis of 0,20 cm' sweat you find out the end point (equivalence point) were reached at the time where 0,32 cm³ 0,050 mol/dm³ silver nitrate was added to the sweat. A:Calculate the molar concentration of chloride in the sweat. Assume that the chloride in sweat comes from dissolved sodium chloride. B:Calculate the number of moles of sodium chloride in 1,00 cm sweat. 1,00 cm of sweat weighs 1,00 g. C:Calculate the mass procent of sodium chloride in sweat Problem 5 In a lab you dissolve a 6,0 mol/dm solution of ethanoic acid by measure out 20,0 cm with a pipette and transferred to a 1000 cm measuring flask. You fill the measuring flask to the mark and shake it. Calculate the molar concentration of ethanoic acid in the diluted solution.
