So to answer this we will use the next procedure:
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
I hope this can help
