We’re being asked tocalculate the actual yield of Mg(NO3)2in the reaction if theefficiency (percent yield) is 30.60%.

You are watching: Assuming an efficiency of calculate the actual yield

The balanced chemical equation is:

Mg + Cu(NO3)2→Mg(NO3)2 + Cu

Respeak to thatpercent yieldis given by:

%Yield=actual yieldtheoretical yield×100

The theoretical yield is not given but we can usage the given information:140.2 g Mgreacts withexcessCu(NO3)2.


Assuming an performance of 30.60%, calculate the actual yield of magnesium nitrate developed from 140.2 g of magnesium and also excess copper (II) nitrate.

Mg + Cu(NO3)2 → Mg(NO3)2 + Cu
