When Ca(NO3)26) is dissolved in water the reaction shown below occurs. Use the mass of Ca(NO3)2(6) in the vial (0.40 grams) and the volume of water needed to dissolve all the solid to calculate the concentration of Ca2 (ag) ions in the Ca(NO3)26) solution. The molar mass of Ca(NO3)2(6) is 164.09 g/mol. (3 points) Ca(NO3)2(9) → Ca (aq)+ 2 NO3 (aq)
