A Chemist measured 184 mL using a graduated cylinder. Based on her experience, the volume did not seem to be correct. This volum

e was again measured using a calibrated standard device, from which it was determined that the volume of the liquid was actually 230.0 mL. What is the % error in this measurement?

Answer:

Percent error = 20%

Explanation:

The percent error is calculated using the following equation:

Percent error = |(approximate value - exact value)| / (exact value) x 100%

In this problem, the approximate value was 184 mL and the exact value was 230.0 mL

Percent error = |(184 mL - 230.0 mL)| / (230.0 mL) x 100% = 20%

Find the no. Of electron involved in the electro deposition of 63.5g of cu from a solution of cuso4
sp2606 [1]
This is a redox reaction, meaning reduction-oxidation reaction. This represents the reaction in one side of the electrode in an electrolysis set-up. First, we find the oxidation number of Cu in CuSO4:

(ox. # of Cu)+ ox.# of S + 4(ox.# of oxygen) = 0
(ox. # of Cu) + (6) + 4(-2) = 0
ox. # of Cu = 2+

CuSO4 ---> Cu + SO42-
Cu2+ + SO42-  ---->  Cu + SO42-
Cu2+ -----> Cu + 2e-   (net ionic reaction)

The stoichiometric equation would be 2 electrons per mole Copper. Copper has a molar mass of <span>63.5 g/mol. Then, it would only need 2 electrons.
