This is a picture of the problems. 

SOLUTION STOICHIOMETRY - super fun - give it a try...remember, if you can determine how many moles are in
a sample, you can use a molar ration - and do stoichiometry! So, with molarity - you can use the MOLARITY
formula and determine how many moles are present in a given volume of a given molarity!!

ions?
2. If you have 50mL of .30 M K,PO, and 50mL of 1.0 M MgCl, how much of the precipitate will form from
the reaction? (Hint: you need to find the limiting reagent first!)
