(b)What will be the concentrations of each of the ions in the mixture after reaction? Put your answers with 3 significant digits.
Ion Concentration (M)
Ca2+ M
Na+ M
PO43- M
NO3- M

Suppose 148 mL of 0.325 M MgCl2 is mixed with 68.7 mL of 0.388 M NaOH and allowed to react completely. Volume change at precipitation can be ignored.



How many grams of Mg(OH)2 will form?
