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 2 significant figures 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?
