    1. V2=M1V1M2=(0.0452)(0.045)0.0955=21.2mL(20)(20)V2=M1V1M2=(0.0452)(0.045)0.0955=21.2mLV_2= \dfrac{M_1V_1}{M_2} = \dfrac{(0.0452)(0.045)}{0.0955} = 21.2\; mL Therefore it takes 21.2 mL of Ba(OH)2Ba(OH)2Ba(OH)_2 to titrate 45.00 mL HNO3HNO3HNO_3.

      THIS PART IS wRONG, Ba(OH)2 has two OH- groups so needs to be divided by 2
