Question

9. What volume of 0.416M Mg(NO_{3})_{2} should be added to 255 mL of 0.102 M KNO_{3} to produce a solution with a concentration of 0.278 M NO_{3}^{–} ions? Assume volumes are additive.

Step 1

When two solutions are mixed with each other, then dilution equation can be represented as follows:

Step 2

The values are given as follows:

Step 3

Suppose the unknown volume is X and as 2 moles of NO3 is present in Mg (NO3)2,...
