A student weighs 2.046 g Cu into a 250 mL beaker at the beginning of the experiment. At the end of the experiment 1.347 g Cu is recovered. Calculate the percent loss of Cu?

Solution:

The loss of Cu at the experiment is: 2.046-1.347=0.699 g.

So, the percent loss of Cu is: $\frac{0.699}{2.046} \times 100\% = 34.16\%$.

Answer: the percent loss of Cu is 34.16%.
