Hi ma'am, such a good explanation, i am from india and here teachers dont exactly teach you the formulas, i dont know why, like the equation mv/1000 was this simple! I watched your video 4 or 5 times and i am so confident now ! 1month back i got my 9th standard results and scored just 40 percent . I was so weak in stoichiometry but now i am so confident and i hope i can atleast score 80% next time .Thankyou ma'am !

I dont get what you did in 14:50 why don't just use 50g?And why did you then multiply the number of moles by the mr of C8H8)

at 14:12 how'd you get 50? because i got 58, please explain to me
