Answer:
The final molarity of nitrate anion in the solution is 0.258 M.
Explanation:
Mass of barium nitrate 1.73 g
Moles of barium nitrate =
1 mole of barium nitrate gives 2 moles of nitrate ions,then 0.00662 mol of barium nitrate will give :
of nitrate ions
moles of nitrate ion added to the solution = 0.01324 mol
Molarity of the barium nitrate solution = 63.0 mM = 0.063 M
1 mM = 0.001 M
Volume of barium nitrate solution = 100 mL = 0.100 L
1 m L = 0.001 mL
Moles of barium nitrate in the solution = n
Moles of nitrate ion in solution = 2 0.0063 × mol = 0.0126 mol
Total moles og nitrate ions = 0.01324 mol + 0.0126 mol = 0.02584 mol
Final molarity of nitrate anion in the solution.:
The final molarity of nitrate anion in the solution is 0.258 M.

Answer:
This is a popular question because it is important. You have 2 Major kinds of substances, or compounds, ionic, and covalent. Covalent compounds usually do not “break apart” in solution, (in fact you have to try and find the right ones to do this), BUT, the IONIC compounds, like salts, held together by their opposite charges do tend to separate in solution.
Take NaCl, sodium chloride. Add waster, and you get Na+ and Cl-. Now if we add methanol, a poisonous alcohol, it simply remains together as it is diluted in water. It is a Covalent compound, where all of the atoms of CH3OH share their electrons, which is very different than being held together by opposite charges.
