Answer:
The answer is 22.5ml
Explanation:
The chamber volume is 500 ml.
So amount of oxygen in chamber at the beginning
=
=105 ml
After the end of hour ; let x ml of oxygen was consumed.
Amount of oxygen at the end of 1 hour =18 %
So,
=0.18
Solving we get ;
105-x= 90-0.18 x
0.72 x =15
x=20.83 ml
So amount of oxygen consumed in the hour =20.83 ml
So answer is A.
