@7RaPeKiNg7 From what I understnad goes like this, you knwo that the number of moles equals as the grams of substance divided per the molecular mass. And he did that and got the number of moles. So he knew in 100 g of substance you have 75 grams of Hg, using the equations you obtain number of moles equals the mass witch is 75 grams divided per the molecular mass of substance which is it 200, and you obtain the number of moles.

8:38 wait, can someone please explain to me the part where he says for every Hg there is 2 Cl? i dont get where that comes from. lets say theres 100g of things and 50g is Hg and 50g is Cl then Hg would be .25 mole and Cl would be 1.4....

Very good video.
I like the way you have an easy going manor which makes it easy to understand what you are teaching.
This will be great for my son whom I am going to be home schooling this year.
Thank you for the effort your expending on these videos. 5/5

Sal, I love all your videos. They've been very helpful, thank you so much. If I could request one thing related to this topic is mass to mole conversions. For example, how do you solve a question such as: What amount of substance is present in 100g of NH3(g)? Again, thank you!
