Answer:
36.92 mg of oxygen required for bio-degradation.
Explanation:
[tex]5C_6H_6+15O_2\rightarrow 12CO_2+15H_2O[/tex]
Mass of benzene = 30 mg = 0.03 g (1000 mg = 1 g )
Moles benzene =[tex]\frac{0.03 g}{78 g/mol}=0.0003846 mol[/tex]
According to reaction 5 moles of benzene reacts with 15 moles of oxygen gas.
Then 0.0003846 mol of benzene will react with:
[tex]\frac{15}{5}\times 0.0003846 mol=0.0011538 mol[/tex] of oxygen gas
Mass of 0.0011538 moles of oxygen gas:
0.0011538 mol × 32 g/mol = 0.03692 g = 36.92 mg
36.92 mg of oxygen required for bio-degradation.
