I rely on videos to help me with getting an understanding of the Core Concepts I'm expected to know. I really enjoy how you explain things thank you very much
@@Rengoku976 yeah, she added .278 instead of .0278, which if you substitute you get the .96 she did. small error but does create uncertainty. just about every chem class i have been too includes such mistakes.
I check also the mole fraction for how many times but it ended up that the mole fraction value is 0.9950 and why is it that your mole fraction is .96? How come ?

I’m sorry but isn’t the mole fraction 0.995?
The lowered vapor pressure then would be 521 torr
yeah same, my answer is also same as yours. 0.995

@@iffandonlyiff6949 Thanks for the explanation 👍

hi Brizo. i think there is a slight mistake but its so little such that at end you would still get the same answer.
3yrs later, I also got 0.9950 and I'm doing A-level. I don't tolerate this slight error😂
