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.
<span>Acetylene is a pure substance so it is homogeneous.</span>
If the pH is 7, the solution is neutral, which means that it is an equal amount of acid and base.
