What is the concentration of nitrate ion in a 425 ml solution containing 32.0 g of mg(no3)2 (m = 148.3)?

Explanation:

Hello,

In this case, we compute the concentration as the molarity of the nitrate ion as the ratio between the nitrate ion moles and the volume of the solution as shown below:

Now, the nitrate ion moles are computed considering that in mole of magnesium nitrate, there are two moles of the nitrate ion:

Finally, the requested molarity turns out into:
