Molecular Mass of Compound.

[tex]\\ \sf\longmapsto Ba_3(PO_4)_2[/tex]

[tex]\\ \sf\longmapsto 3(137u)+2(39u+4(16u))[/tex]

[tex]\\ \sf\longmapsto 411u+2(39u+64u)[/tex]

[tex]\\ \sf\longmapsto 411u+2(103u)[/tex]

[tex]\\ \sf\longmapsto 411u+206u[/tex]

[tex]\\ \sf\longmapsto 617u[/tex]

  • Molecular mass of O in compound=16(4)=64u

[tex]\\ \sf\longmapsto Mass\%\:of\:O[/tex]

[tex]\\ \sf\longmapsto \dfrac{64}{617}\times 100[/tex]

[tex]\\ \sf\longmapsto \dfrac{6400}{617}[/tex]

[tex]\\ \sf\longmapsto 10.3\%[/tex]
