18g glucose $\left( {{C_6}{H_{22}}{O_6}} \right)$ is added to 178.2 g water. The vapor pressure of water (in torr) for this aqueous solution is.

The Henry's law constant for $O_2$ in water at $25^\circ C$ is $4.34 imes 10^4$ atm. If the partial pressure of $O_2$ in air is 0.2 atm, calculate the concentration (in molarity) of dissolved oxygen in water in equilibrium with air at $25^\circ C$. Assume the density of the solution is approximately equal to that of water (1 g/mL).
