Answer 1

`\% O=24.6\%`

Step-by-step 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:

`\% O=(2*16.00)/(130.18 ) *100\%\\\\\% O=24.6\%`

Best regards!
