HC2H3O2(aq) + Ba(OH)2(aq) + ----> H2O(l) + Ba(C2H3O2)(aq)

anzhelika [568]

The balanced chemical reaction is:

2HC2H3O2(aq) + Ba(OH)2(aq) + ----> 2H2O(l) + Ba(C2H3O2)2(aq)

We are given the amount of HC2H3O2 to be used in the reaction. This will be the starting point for the calculation.

 0.461 mol HC2H3O2 ( 1 mol Ba(OH)2 / 2 mol HC2H3O2 ) = 0.231 mol Ba(OH)2
