21. A student correctly determines that 17.1 grams of sucrose are needed to make 50 mL of a 1 M sucrose solution. When making this solution in lab, the student measured 50 mL of water and
massed 17.1 grams of sucrose. The student then mixed the two together into a new beaker. The
student's resulting solution was not 1 M sucrose as intended. After the student mixed sucrose and
water, the resulting solution was poured into a graduated cylinder and it read 62 mL.
