Question

III. Adding a complexing agent such as pyrophosphate (OsPOPOs) or triphosphate (P,010) to detergents prevents the magnesium and calcium salts found in "hard" water from precipitating (to form "scum") because the equilibrium constant for complex-ion formation is large, viz: 2+ +4 Were one to add 5.000 mL of 0.0613-MNa4(O;POPOs) to 25.00 mL of 0.0115-M Ca(NO,)2 calculate (i) the mmols of Ca2 ions that remain uncomplexed in the resulting solution and (ii) the percent of Ca ions that are uncomplexed from the original solution. Assume additive volumes and retain four decimal digits in your reaction table (worked in mmols). 10 points. 2+ rxn table in mmols (four decimal digits):

Correct answer is .0114 mols and 3.95%

Need full explanation on how to get there please!
