The percentage yield shows how much product is obtained compared to the maximum possible mass. Molar gas volume can be used to make calculations about reactions between gases.
The percentage yieldA measure of how much product is actually made, calculated from: 100 脳 (actual yield) 梅 (theoretical yield). is calculated using this equation:
The percentage yield can vary from 100% (no productA substance formed in a chemical reaction. has been lost) to 0% (no product has been made).
Question
Copper oxide reacts with sulfuric acid to make copper sulfate and water. In an experiment, 1.6 g of dry copper sulfate crystals are made. If the theoretical yieldThe maximum possible mass of a product that can be made in a chemical reaction. is 2.0 g, calculate the percentage yield of copper sulfate.
actual yield = 1.6 g
percentage yield = \(\frac{1.6}{2.0}\) x 100
percentage yield = 80%
Question
In an experiment, the theoretical yield is 3.2 g but the actual yield is only 2.4 g. Calculate the percentage yield.
