Find out the actual concentration of the sucrose

Reference no: EM13184605

A student, who has not learned properly how to prepare solutions, added 51.3 g of sucrose (FW = 342.31) to exactly 150.0 mL of dH2O and assumed that a 1.0 M solution had been prepared. The total solution volume increased to 180.0 mL after the sucrose was dissolved and the solution was thoroughly mixed. Determine the actual concentration of the sucrose solution prepared by the student. What did the student do wrong? If the solution had been prepared correctly to the desired 1.0 M concentration, what volume of this stock should be diluted to prepare 100.0 mL of a 1.0 mM working solution?
