CH3COOH and multiply the moles with its molecular formula then u would have the net amount of the acid.
Now we can also calculate the mole of acid left in 5L=C*5L
So we can get C from the above formula and after that (C-Cα) would be the net concentration of acetic acid.
α= 0.01(given 1%)
Ka=C(α)2
C-C*α......Cα......Cα+10-7. .(at equilibrium)
C...........0.......10-7. (initially)
CH3COO- + H+
