So to answer this we will use the next procedure: <span>First balance the equation:
2 C6H5OH + 15 O2 --> 12 CO2 + 6 H2O Phenol (C6H5OH) reacts with O2 in a 2:15 ratio. This means:
moles phenol 2 / moles O2 = 2 / 15
moles phenol = (2/15)*0.200 = 0.0267
Molar mass of phenol is 94 g/mol Mass of phenol would = 0.0267*94 = 2.5 g </span>I hope this can help
