Answer:
112 mL
Explanation:
The formula for percent by volume is

If you have 250 mL of a solution that is 44.8 % v/v,

Actually, the ionic equation for this is a reversible
equation since codeine is a weak base. Any weak base or weak acids do not
completely dissociate which makes them a reversible process. The ionic equation
for this case is:
