When does the oxygen dissociation curve shift to the right?

Assertion : Oxyhaemoglobin dissociates near the organ tissue due to Bohr effect and oxygen is released.
Reason : Increased $CO_2$ concentration reduces the affinity of haemoglobin for oxygen.

Approximately what amount of $O_{2}$ reaches the tissues via $100 \ ml$ of blood (in $ml$)?
