The Henry's law constant for 02 dissolved in water is `4.34 xx 10^(4)` atm at certain temperature. If the partial pressure of `O_(2)` in a gas mixture that is equilibrium with water is 0.434 atm, what is the mole fraction of `O_(2)` in the solution?

Options

A. `1xx10^(-5)`
B. `1xx10^(-4)`
C. `2xx10^(-5)`
D. `1xx10^(-6)`
