A $9\mathrm{.}00$ L tank at $25\mathrm{.}1C$ is filled with $7\mathrm{.}26g$ of boron trifluoride gas and $17\mathrm{.}0g$ of dinitrogen monoxide gas. You can assume both gases behave as ideal gases under these conditions.

Calculate the mole fraction of each gas. Be sure each of your answer entries has the correct number of significant digits.
