In this lesson, we will learn how to identify the limiting reagent and calculate the percentage yield of desired products based on the actual and theoretical yield.
Sample Question Videos
Sodium nitrate was dissolved in water at to produce a saturated solution. The solution was filtered to remove undissolved solid and then cooled to to precipitate the sodium nitrate. The solubilities of sodium nitrate at 80 and are 148 g/L and 73 g/L respectively. Calculate the percentage yield for this recrystallization method.
Reaction of 1.274 g of aqueous copper sulfate with excess zinc metal produced 0.392 g of copper metal according to the equation shown.
Calculate, to the nearest whole number, the percentage yield of this reaction.
A student treated 15 g of copper(II) oxide with excess hydrochloric acid and purified the copper(II) chloride product by recrystallization. The final mass of pure copper(II) chloride was 11 g. What was the percentage yield?
