Mole Fraction Practice Problems

Here, we work through two practice problems involving mole fraction. Mole fraction is calculation that is used to determine the concentration of components in a mixture. The number of moles of a certain component is divided by the total number of moles in the mixture. When the numbers are not given in moles, you first have to convert from gams to moles by using the molar mass. This video will be helpful to people taking chemistry classes in both high school and college/university, and also preparing for exams like the AP, A-levels, SAT, O-levels, MCAT, DAT, OAT, IGCSE, ICSE, CBSE, JEE, NEET, and IB.

Me too from Pakistan 🇵🇰

[@MukeshPal-iq2os]

Thank you sir , please make a bunch of video on concentration term ( molarity, molality , mole fraction, normality , formality etc ) world's needed you as a teacher , please make continue video on chemistry
We are thankful to you 🙏🫡

I am very happy I found your videos Tyler, I was so so lost in Chemistry but your videos are very helpful. Do you do individual tutoring?

[@ogbennamunachi1275]

Wow
Keep on striving sir.
Your student from Nigeria

in the middle of preparing PE exam, great lecture to learn mole fraction

[@user-lu1mq5ks1e]

Thanks a lot sir ❤

Thank you 👍

Sir please upload a video on molecular orbital theory and to identify para and dia magnetic HOMO LUMO 🙏

Should the final answer be in 3 decimal places or it depends in the problem given?

Hi where are you from sir plZz reply ❤

[@thegoodzheinn1659]

Um.. what happened to the significant figures every final answer, Sir? Or when do we apply significant figures? If I'm not wrong, I think we have 4 sig figs for this? And we applied it po for the molar mass of the compound however, not in moles?

[@thegoodzheinn1659]

Though we'll only get the same answer, XsubCH3OH = 0.1549.. or 0.155 and for XsubH2O = 0.8448.. or 0.845, would it be okay to use 2 decimal places from the conversion of grams to moles and use it for our mole fraction formula?
