if Fe(NO3)3 is dissolved in enough water to make exactly 323 ml of solution, what is the molar concentartion of nitrate ion g

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.

 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.
