Thank you very much I always used to find it so difficult and you made it seem so simple. I tried the sample questions after your explanation and got all of the correct. Thank you again. :)
Another useful way you can view question 3 is by simply multiplying the molecular weight by two(136.09 x 2 = 272.18) so that you can see how much grams would be in a 2L solution to that is 1M, and then divide the given numbe(83.7) by your new 1M gram total(the 272.18) to get the same answer but in less steps and thinking.
I want to ask something. supposed I want to make a phosphate solution form KH2PO4 anhydrous. to a phosphate solution of 300mg/L should I just ad 0.3 gram of KH2PO4 into a liter of DI water or I have to do some calculation? thank you!
So, 58.4g NaCl solute into 1L solvent, or 58.4g NaCl solute into 1L - volume taken up by 58.4g NaCl? I imagine the volume of the solute is so tiny as to be negligible. However, this issue always bugs me. Thanks for your answers in advance, fellow viewers.
yes I think she made mistake. its mass of solute over 1L solvent not solute. the solute is initially a solid and is not measured in liters. It is what you are distilling or titrating from the solution.
Ive been in lab class for over a month and the explanations given in this video, have been what ive needed for a long time.
I'm so happy that I finally understood stuffs that I've been banging my head for...
Your explanations are so simple. Thank you so so much!
Dear Madam, thank you so much for the quality of your teaching.
The best explanation i've ever had

Best way to understand dilutions. Thanks
You are a life saviour. God bless you
Amazing explanation and it increased my confidence.
Thank you!
Thank you for simplifying this for us.
Well explained with examples. Thank you 🙏

Very useful video. loved it. thank you
Great work....explained really understandable...

i got it very clearly...thankyou mam
thank u so much...very well explained...
thanks, it was very helpful
Thank you, thank you, thank you, thank you and thank you.
Thank you very much!
tanku so much.:-):-)..rly helpful...
You are the best
I have understand!!!!!! than you for your simplicity
Thanks a lot ma'am... thank you so much
thank you. 👍
Thank you ma'am 😊
Wish my chemistry teacher taught me in this way😂😂😂😂,,,just wondering why some teachers make things complicated yet in the actual sense dea simple,,,,,
All super clear, except the last step of last question, please if anyone got the same answer as mam explained, please let m know, Thanks in advance.

Nice explains
wow..its so easily explained..i used 2 always get confuse
thank you very much mam
Thank u
Shouldn't the heading be 1l of solvent ,rather than solute??
Can you explain real time pcr, working principles, protocol, and calculation..because your explanation was really helpful..
Very good except camera angle. Well explained and i defiantly need some serious catching up with this/
❤️
Nice madam
Because in last step it was 1/3.25 then you can get the answer 0.31.
You don't explain some numbers how you get it but it would be much simpler by showing cross multiplication. Anyways thanks for your video.
I can now only complete molarity calculations in a Scottish accent
