The mass percent of oxygen is 32.82%.
<h3>What is a noble gas?</h3>
A noble gas is member of group 18 in the periodic table. The members of this group are known not to be reactive and they do not easily form compounds. However, there have been few compounds of the members of group 18 that have been reported.
Let us now calculate the relative molecular mass of xenon tetraoxide.
Xe + 4 (O)
131 + 4(16) = 195
Given that the mass of oxygen in the compound is 64, the mass percent of oxygen in xenon tetroxide is obtained from;
64/195 * 100/1
= 32.82%
