Answer:
The yield of the purification is 79.7%
Explanation:
Hi there!
5.731 g nickel metal could be produced by the student if the yield of the purification would be 100%. Instead, 4.567 g was obtained. Then, the yield of the purification can be calculated as follows:
4.567 g Ni · (100% / 5.731 g) = 79.7%
The yield of the purification is 79.7%
