Great video, thank you. I want to prepare a 100 ml 25% v/v glutaraldehyde solution and the glutaraldehyde available is 50% wt% glutaraldehyde in water, MW= 100.12 g/mol, d= 1.106 g/ml. Would I be correct for using C1V1= C2V2. The answer I get is 50 ml of 50% glutaraldehyde in 100 ml to give 25% v/v glutaraldehyde. Thanks
You absolutely must make sure your initial and final concentrations are in the same units, otherwise the units won’t cancel properly (dimensional analysis). Thanks for the question!
Probably true for some, depending on the grade level. This was a lesson left with my grade 11 chemistry class while I was away. Some students are able to grasp concepts right from the get-go, while others struggle and need the content broken down and require context.
Hello! I make these lessons for my own classes on days where I am away. The lesson was taught face-to-face in class with my students, so you won't be able to find a video relating to it.
best explanation I've seen. Saying Hi from the U.K!
@@giakolou2876 wooo Canada here. Are we being forgotten? lol

THANK YOU!!!!!!! SIMPLIFIED AND EASY
This was so helpful!
thank you so much i needed that quick revision
Amazing! Glad to help!
How I convert the 65% methanol solution to 80% methanol solution?
How much ml of methanol required?

How to make simple dilution from 0.5g dm-3 stock solution?
thank you, this helped me so much!
Thank you 🙂

You did not convert the units
There is no need, as units of milliliters will cancel out (dimensional analysis).
Finals be like :(
great
thanx miss
Does it matter if C1 and C2 have different metrics? Like do I have to convert if C1 is in ug and C2 is in mg?

@@theresamitchell1653 Thank you so much 😊. Your video is great and it actually made everything make sense. Thanks 🙏.
thank youu
This could have been taught in less than 10 mins. It was helpful but for future reference, it would just be best to get to the point.
