The plastic industry uses large amounts of phthalic anhydride `C_(8)H_(4)O_(3)`, made by the controlled  `C_(10) H_(8) + (9)/(2) O_(2) rarr C_(8) H_(4) O_(3) + 2 CO_(2) + (5)/(2) H_(2) O`Since some of the naphthalene is oxidised to other products, 80% yield is obtained. What weight of phthalic anhydrid would be produced by the oxidation of `256 g` of `C_(10)H_(8)`.  `[Mw "of" C_(10) H_(8) = 128, Mw "of" C_(8) H_(4) O_(3) = 148]`
