What is the concentration of NO₃^- ions in a solution prepared by dissolving 30.0 g of Ca(NO₃)₂ in enough water to produce 300.mL of solution? A) 0.305 M B) 0.609 M C) 0.806 M D) 1.22 M

Question

Quizplus · Accepted Answer

The molar mass of Ca(NO3)2 is 164.1 g/mol. Dissolving 30.0 g gives 0.183 mol of Ca(NO3)2. Since each formula unit produces 2 NO3- ions, the concentration of NO3- is 2 * 0.183 mol / 0.300 L = 1.22 M.
