200 ml of oxygen is present in
Answers
Explanation:
On room air and with a haemoglobin of 150, every litre of blood in a normal subject carries about 200ml of oxygen as oxyhaemoglobin and about 3ml of oxygen as dissolved gas.
Answer:
125.0 ml
We have 100 ml mixture of CS
2
and CO.
Let x ml of CO in the mixture and (100−x) ml of CS
2
in the mixture
We have the following combustion reactions.

Total volume of O

Let volume of O

used =y
→3(100−x)+

x
=y
on simplification we get
5x+2y=600
−−−(1)
Volume of O

remain unreacted =200−y
After combustion reaction total volume of mixture of gases is
(100−x)+2(100−x)+x+(200−y)=245
⇒2x+y=255
⇒
4x+2y=510
−−−−(2)
On Solving eqn (1) and (2) we get
x=90 & y=75
Volume of O

remains unreacted =200−y
=200−75
=125 ml
