Calculate the percent error in the experiment using the experimental mass of CuO and the theoretical mass of CuO. The percent error is defined as follows.?
This is in Short AnswerDecomposition of Malachite %error= experimental value-theoretical value/theoretical value X100
My notes for the lab are: We placed an empty crucible onto the balance and recorded it's mass to be 88.000g.
We then removed the crucible and added 10g of copper (ll) carbonate hydroxide and placed it back on the balance to recorde the new mass to be 98.000g.
We then took a Bunsen burner and put the crucible containing the 10g of copper (ll) carbonate hydroxide on top at low heat.
The color before heating was bright green. The color after heating on low heat was black.
The mass of the crucible after heating under the Bunsen burner was 95.195g
