In PV = nRT, n is the number of moles. When 8 grams of oxygen are present,
n = 8/32 = 1/4
So PV = RT/4
Explanation:
Obviously there's an exothermic reaction going on, which suggests a neutralisation reaction. A dark blue precipitate is formed, which could be a copper salt. So a new substance formed.
