The given question is incomplete. the complete question is : If 5.15 g is dissolved in enough water to make exactly 323 ml of solution, what is the molar concentartion of nitrate ion.
Answer: The molar concentartion of nitrate ion is 0.195.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Given : 5.15 g of is dissolved
Volume of solution = 323 ml
where,
n= moles of solute
= volume of solution = 323 ml
As 1 M of gives 3 M of
ions.
Thus 0.065 M of gives =
of
ions.
The molar concentartion of nitrate ion is 0.195.
