*CORRECTION OF ERROR*
Our Beloved VIEWERS,
Thank you for all your constructive criticisms. It shows that you have our interest at heart and want us to be better. It is much appreciated!🙏 Our attention has been drawn to an error in the solution to the last question in this video, in which we were asked to calculate the amount of silver deposited, and we mistakenly interpreted it as the mass. We sincerely apologize for this error, and take full responsibility.

To this end, kindly note that the correct answer to that question is 0.113 mole of Ag which is obtained by dividing the calculated mass of 12.221 g by 108 g/mol, the molar mass of Ag, i.e.,
number of mol of Ag deposited = 12.221 g /108 g/mol = 0.113 mol.
Thank you for your understanding and continued viewership.

Regards,
The Science Chef Academy Team

Amount means moles, not gram. Amount of silver deposited is 0.113moles

But amount of silver I thought should be in moles

[charlesoffiong]

Good job, the Science Chef! But in the last, I thought you were asked to calculate the "amount" and not the "mass" of silver deposited. So, the answer should be in moles and not grammes. Please correct that, sir!

When should we expect the correction to Q2 - Q5?
