Because we say humid air “feels” heavier, more dense, more oppressive. ... Technically there is no direct connection between air pressure and humidity, humidity is the amount of water vapor in the air or air parcel. Air pressure is the weight of the air in a column. The only true connection would be the temperature.
Answer:
36.92 mg of oxygen required for bio-degradation.
Explanation:
Mass of benzene = 30 mg = 0.03 g (1000 mg = 1 g )
Moles benzene =
According to reaction 5 moles of benzene reacts with 15 moles of oxygen gas.
Then 0.0003846 mol of benzene will react with:
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.
