Answer:
[tex]\% O=24.6\%[/tex]
Explanation:
Hello!
In this case, since the by-mass percent of an element in a compound is computed by taking into account its atomic mass, the number of atoms in the molecules and the molar mass of the compound, we can write:
[tex]\% O=\frac{2*16.00}{130.18 } *100\%\\\\\% O=24.6\%[/tex]
Best regards!
