<span>we know that it takes 2 moles of HNO3 to neutralize and each mole of Ba(OH)2 and the total number of moles of Ba(OH)2 to be neutralized is
23.4*10^(-3) litres * 0.65 mol/litre
= 15.21*10^(-3) moles
[ 2*15.21*10^(-3)
= 30.42*10^(-3) moles] of HNO3 in a volume of 42.5 ml
The molarity is 30.42*10^(-3) moles / 42.5*10^(-3) litres
= 0.72 C
hope it helps

Answer:
No element shares the same atomic number. The atomic number of every element is unique to itself, just like a fingerprint is unique to a human. The atomic number of element allows us to identify it, like how we can identify a person from their fingerprint.
