Explanation / Answer

from the reaction t is clear that one mole of Ba(OH)2 required 2 moles of HNO3

no of moles of Ba(OH)2 = Molarity x volume in liters

= 0.15 x 0.0443

= 0.0066 moles

Molarity of HNO3 = no of moles / volume in liters

no of moles of HNO3 = no of moles of Ba(OH)2 then only nuetralisation will takes place

so no of moles of HNO3 = 0.0066

Molarity of HNO3 = 0.0066 / 0.11

= 0.0604 M
