What is the concentration of nitrate ion in a solutionmade by mixing 100 mL of a 0.200 M HNO3 solutionwith 200 mL of a 0.100 M solution of Mg(NO3)2?
Added by Heather M.
Step 1
First, we need to find the moles of nitrate ions (NO3-) contributed by each solution. For the HNO3 solution: Moles of HNO3 = Molarity × Volume = 0.200 mol/L × 0.100 L = 0.020 mol Since there is 1 nitrate ion in each HNO3 molecule, moles of NO3- = 0.020 mol For Show more…
