    Please see the attached file.

    1. Rewrite and balance the reaction:
    C5H11OH + 7.5O2 = 5CO2 + 6H2O

    MW (C5H11OH) = 5*12+12+16 = 88 (g/mol)
    MW (O2) = 32 (g/mol)
    MW (H2O) = 18 (g/mol)

    According to reaction balance, 1 mol of C5H11OH reacts with 7.5 mol of O2.
    Number of mole of C5H11OH = 230/88 = 2.61 (mol)
    Thus number of mole of O2 required = 2.61*7.5 = ...
