Problem

Two flasks contain aqueous glucose solutions. Flask X:

0.30\,\text{mol}

glucose in

250\,\text{mL}

; then water evaporates until the volume is

200\,\text{mL}

. Flask Y:

0.40\,\text{mol}

glucose in

350\,\text{mL}

; then

50\,\text{mL}

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.
