On an average 15 gm of haemoglobin (Hb) is present in 100 ml of blood. 1 gm Hb can combine with 1.34 ml of O2. Thus 100 ml of blood carries approximately 20 ml of O2 (19.4 ml to be exact).

Q. What amount of $O_{2}$ does $100$ ml of blood carries on an average?

$28$ ml

$20$ ml

$35$ ml

$13$ ml

On an average $15 g m$ of haemoglobin $(H b)$ is present in $100 m l$ of blood. $1 g m H b$ can combine with $1.34 m l$ of $O_{2}$ . Thus $100 m l$ of blood carries approximately $20 m l$ of $O_{2}$ ( $19.4 m l$ to be exact).
