Dilution Series: How to answer exam Qs on the PRACTICAL method and dilution series MATHS questions.

[@evaboukouri1245]

I had literally never got a dilution series question correct, and I attempted one after this video and I got the right answer. Thank you so much!!!!!!!

[@MissEstruchBiology]

yaaaaay 🙌🙌🙌🙌 I love that

[@user-nd2zs2ic6k]

i literally used to struggle with this, this has helped SO much thank YOU!!

[@MissEstruchBiology]

So pleased this has helped you get your head around this 😀

[@amirbatayi3750]

OMG each and every single video of you is helpful, I used to struggle with dilution series as It was hard to imagine it I guess you made it so simpler

[@MissEstruchBiology]

ah yeah a tough topic! I'm so glad it's helped 😁😁

[@davidmkwizu76]

7:34 but the concentration is in dm³ so why don’t we multiply the c2 by 0.02dm³

[@at.8449]

you're correct, she just decided to calculate it in cm3

[@permanentblooms5072]

Thank you sm, this was so needed for my mock tomorrow!

[@MissEstruchBiology]

Ah great! Really hope it helps you gain some extra marks. Good luck 😊

[@charliebrett7510]

Good luck Lucy haha

[@Sara-sc6nm]

Thank you so much your videos are literally amazing!!!

[@MissEstruchBiology]

aww thank you so much. Glad you find them helpful! Good luck

[@ImranAwan-n9s]

Does this relate to the plasma membrane required practical?

[@yagmurxx869]

on the math question, the v1 value was cm rather than dm like the concentration. does it matter if it was to be the same, like both dm?

[@chinonyeremkonkwo5]

Hi, why isn't 0.08moldm-3 converted into cm3?

[@sachinothendee7186]

Are you arteta out?

[@nartha106]

can you please help !!!! how did you get 9 parts of water?

[@ofentsemassinga1952]

About to do this in an hour for marks 😁✌

[@MissEstruchBiology]

Good luck 🤞🤞🤞

[@MissEstruchBiology]

You're welcome. I really hope it helps 😊

[@aliananda6912]

hi !! i just wanted to say THANK YOU because serial dilutions was in the ocr paper i sat yesterday and i would’ve left it blank if i hadn’t watched your video !!! 🥲🥲🥲

[@aluminiumoxide8750]

Is proportional dilution same as stock dilution ?

[@MissEstruchBiology]

Proportional is when you measure out the exact solute mass and volume of solvent and mix to make the desired concentration, so that is different to serial dilutions.

[@ironman8961]

So helpful thanks

[@MissEstruchBiology]

You're welcome 😊

[@ZuzannaPodgorska]

really helpful!

[@MissEstruchBiology]

so pleased it helped you !!

[@leaquarm6768]

Your amazing I love u

[@MissEstruchBiology]

Thank you!

[@ArnavPadhi]

Plz make videos on primer stock solutions calculations for PCR?

[@sobia9963]

UGH i don’t think I’ll ever wrap my head around serial dilutions they confuse me sm:((

[@ris4314]

TMMM

[@mino3926]

miss do you have a video on proportional dilution?

[@MissEstruchBiology]

Hello, No i don't I'm afraid.

[@MrMidoo2010]

Fabulous as usual, but still forget about O level 0610 syllabus🤥 NO WAY MISS.

[@MissEstruchBiology]

Hello Glad you liked it. Sorry if there has been some miscommunication about uploading a different spec. I'm on maternity leave and also KZbin isn't my full-time job, so it takes a long time to get through all videos. I have looked through the specification you sent and most of the content is covered by the existing videos, just in a different order, but unfortunately it's not possible for me to promise any time frame I can do more from that spec, I'm still focusing on creating content for the students at my school.
