In year $2243,$ based on samples collected during missions to a moon of exoplanet Kepler $433b,$ the elemental composition of the soil of

that moon on a mass basis is:

Assume that the average atomic mass of the Other component is $100\mathrm{.}0\frac{g}{m}ol$ and calculate the mole fraction of oxygen in the soil.

$x_{\text{o}\text{x}\text{y}\text{g}\text{e}\text{n}}-i$
