How do I start to solve this? I am so confused
What moles of 0.416 M Mg(NO3)3 should be added to 255mL of 0.102 M KNO3 to produce a solution with the concentration of 0.278 M NO3- ions?
Expert Solution
Step 1
Note: Given formula is incorrect: Mg(NO3)3
As charge of Mg is always +2, therefore Correct formula: Mg(NO3)2
Given:
Concentration of Mg(NO3)2 = 0.416 M
Concentration of KNO3 = 0.102 M
Volume of of KNO3 = 255 mL = 0.255 M
Total concentration of NO3- of solution = 0.278 M
let the volume of Mg(NO3)2 be 'x'
