Q.The vapor pressure of water at $20^{\circ}C$ is $17.5 \text{ mm Hg}$ . If $18 \text{ g}$ of glucose is added to $178.2 \text{ g}$ of water at $20^{\circ}C$ , the vapor pressure of the resulting solution will be:

17.325 \text{ mm Hg}

15.750 \text{ mm Hg}

16.500 \text{ mm Hg}

17.000 \text{ mm Hg}

The correct solution involves applying the fundamental concept to derive the final value step by step...
