This helped me so much. I overthink things and this helped my style of learning. (Dumbing it down)

The way you taught the strategy is very well done, although I think the answer may vary from yours when taking significant figures into account.

Professor Organic Chemistry Tutor, thank you for a short video/lecture on How to Calculate the Average Atomic Mass of an Element given the required percentage abundance of each Isotope. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

This teacher is really good at teaching. He doesn't say "you should be able to solve it by now" like my tutor do
