hi im a bit confused as to why u didn't first find out the mole fraction in question 2 and then times it by total pressure to find partial pressure. can u pls explain :)
Hi, I'm not entirely sure which question you mean. Do you mean (c)(ii)? If so, you're correct in how to do it. Mole fraction x total pressure gets you the partial pressure. I just did total pressure x mol fraction without ever knowing (or writing down) the decimal value for mol fraction 😃
Your question walkthrough videos are so helpful - thank you so much for them!
Thanks for the kind feedback 😀
This video was so useful. Thank you so much ✨
That's great to know! Thanks for the feedback 😀
thank you!
You're very welcome! Glad it's useful 😊
