Problem: A solution is made by mixing 15.0 g of Sr(OH)2 and 60.0 mL of 0.210 M HNO3.Calculate the concentration of NO3- ion remaining in solution.

FREE Expert Solution

We are asked to calculate the concentration of NO3- ion remaining in solution.


Sr(OH)2 + 2 HNO3 → Sr(NO3)2 + 2 H2O


Calculate the concentration NO3- ion using both reactants: 

Molar mass Sr(OH)2 = 121.64 g/mol
