hydroxide with phosphoric acid where 10.0 mL of 0.150 M magnesium hydroxide is mixed 15.0 mL of 0.100 M phosphoric acid. The chemical reaction is provided below. Mg(OH)2 (aq) + H3PO4 (aq) →Mg3(PO4)2 (s) + H2O (l)
Consider the reaction of magnesium hydroxide with phosphoric acid where 10.0 mL of 0.150 M magnesium hydroxide is mixed 15.0 mL of 0.100 M phosphoric acid.
The
Mg(OH)2 (aq) + H3PO4 (aq) →Mg3(PO4)2 (s) + H2O (l)
If the percent yield of this reaction was found to be 83.4 %. What is the actual yield in grams of the ionic salt that is obtained from this reaction?
First calculate moles of each reactant by multiply MOLARITY and volume then find out limiting reagent which is in less quantity so here is Mg(OH)2 limiting reagent. it will be finished in the chemical reaction
Using mole-mole relationship calculate mole of Mg3(PO4)2 formed
Then calculate mass of Mg3(PO4)2 by multiplying molar mass to the mole.
