Problem
Two flasks contain aqueous glucose solutions.
Flask X: 0.30mol glucose in 250mL; then water evaporates until the volume is 200mL.
Flask Y: 0.40mol glucose in 350mL; then 50mL of water is added.
After these changes, which statement correctly compares the final molarity of the solutions?
(a) Flask Y is more concentrated than Flask X.
(b) Both flasks have the same molarity.
(c) Flask X is more concentrated than Flask Y.
(d) The final molarity cannot be determined from the information given.
