4b(iv) Remember 10.0 cm3 pоrtiоns оf the sаturаted bаrium hydroxide solution were placed in conical flasks and titrated with hydrochloric acid. The equation for the reaction in the titration is: Ba(OH)2 (aq)  +  2HCl (aq)  →  BaCl2 (aq)  +  2H2O (l) Using the equation, calculate the number of moles of barium hydroxide in 10cm3 during this titration. Calculate the concentration of barium hydroxide, in g dm−3, giving your answer to an appropriate number of significant figures. (3)   c = n/V
