5) A student correctly determines that 17.1 grams of sucrose are needed to make 50 ml of a 1M
solution of sucrose. When making this solution in the lab, the student measured 50.0 ml of water in
a measuring cylinder and added that to a beaker. Then the student massed 17.1 grams of sucrose
and added it to that beaker. She then mixed the solution well and poured the resulting solution into
a graduated cylinder. To her utter shock, the volume of the solution was now 62.0 mL. Explain what
happened.
Describe the steps the student should have taken to prepare a 50.0 ml solution of
1M sucrose.
6) What volume of 0.10 M solution can be prepared using 11.6 g of NaCl?
