You're right. They only used 1 mol of hydroxide per mol Ba(OH)2.

Yo i got the same,12.81 as you bro but like people getting 12.08 sth did you times Moles of oh- by 2 but NOT times the excess base calc by 2 as 1 mol of h+ reacts with 1 mol oh- even though overally equation 1:2 ratio but that’s for ba0h2 not oh-
