How much higher is the affinity of carbon monoxide for hemoglobin compared to oxygen (in $\times$)?

During oxygen transport,the oxyhaemoglobin at the tissue level liberates oxygen to the cells because

Approximately $97\%$ of $O_2$ is transported by $RBCs$. The remaining $3\%$ is transported by:

During the transport of gases,to maintain the ionic balance,chloride ions shift from

Haemoglobin $(Hb)$ transports oxygen from the lungs to tissues. The partial pressure of oxygen in the lungs is different from that in the tissues. Each $Hb$ can bind to up to four oxygen molecules. Suppose we have an equal number of $Hb$ and oxygen molecules,and all the oxygen molecules are in a bound form. Then,which of the following is true?

Under normal physiological conditions,every $100 \,mL$ of oxygenated blood delivers approximately ......... $mL$ of $O_2$ to the tissues.
