It's difficult for me to grasp an understanding of these problems in class right now since my teacher teaches a different lesson every day, but watching these videos have helped me a lot with my Chemistry unit tests.
Having to learn this on KZread because the teacher isn’t even here and expects us to know this. Great
I understand him more than my teacher :/

Using you're vid's to study for my chem test on monday, they're so much easier to understand than my actual professor who does one example and expects us to then just know it.
I truly, truly appreciate what you do here. THANK YOU
A big thank you sir I really don't know what my chemistry results will look like if not for this.

That last part, a easier way would be to multiply the 14.01 times the 100 then divide the total by the 13.32%
I calculated NO2 together and ended up with the same final answer and it all added up to 100%. Would it be considered incorrect if I didn't calculate it separately?

How could I know how many sig fig at the answer ?
How about if its only Ca?
how is he getting the molar mass for hydrogen as 1.008?
Question. The percentage of oxygen in Sulphur IV oxide (S =32,O=16) Please show working thanks
O my your the best teacher your iven good than my teacher lol
In the first example, why are there not 5 sig figs in the final answer but rather only 3?
