[answerhappygod]

A 6.400 g sample containing chloride ions (MW=35.45 g/mol) was
dissolved in 50.0mL of distilled water. A 15.0 mL aliquot was
taken, and was further diluted to 50.0 mL using distilled water.
The diluted solution was then titrated using a 0.0989 M AgNO3
solution, and it consumed a total of 31.9 mL of the titrant in
order to reach the end point. a.) What is the concentration of the
undiluted chloride solution? Round off to three (3) significant
figures. b.) What is the % (w/v) concentration of the undiluted
chloride solution? Round off to two (2) decimal points. c.) What is
the % (w/w) of Cl- composition of the sample? Round off to two (2)
decimal points.
